System Requirements Document for bulls-bayou-retreat

1. Introduction

Bulls Bayou Retreat is an off-grid campsite on the Texas Gulf Coast in Port Lavaca, TX. The product is a website with a full booking system that lets prospective campers discover the retreat, browse its six tent and cabin sites, check availability for a requested date range, and complete a reservation for a specific site and stay period. It also gives the operator of the retreat a protected surface for reviewing incoming bookings and keeping allocation across the six sites accurate.

The audience is saltwater kayakers, birders on the Great Texas Coastal Birding Trail, duck hunters, families with kids and pickup trucks, and weekend tent campers who want a fire, a flat pad and no power pedestal. The site should read like a hand-painted sign at the gate, a laminated map on the office wall, and a booking form that just works — not luxury glamping and not a corporate resort.

The product intent is narrow and specific: present this one place honestly, and let a Guest turn interest into a confirmed reservation without friction, while the Campsite Owner/Manager keeps a clean, up-to-date record of who is on which pad.

2. System Overview

Bulls Bayou Retreat is delivered as a first-party web application with custom UI and application-owned identity. The current delivery covers:

• A public, anonymously reachable Landing surface that explains the retreat, its Port Lavaca off-grid setting, and its tent and cabin sites before booking.
• A public Sites browse destination covering the six tent and cabin sites.
• A focused Availability destination for checking a selected campsite against a requested date range.
• A Booking destination for completing a reservation for a chosen tent or cabin site and stay period.
• Guest self-service enrollment (Sign Up) and shared returning-verification (Login).
• A protected Reservations destination for the Campsite Owner/Manager to review incoming bookings and maintain accurate allocation across the six sites.

Actors are the Guest (a prospective camper) and the Campsite Owner/Manager (the operator of the retreat). The booking system is backed by server-side persistence so that reservations, site allocation and availability remain durable and consistent across sessions and across both personas.

Narrow exclusions: the campground is off-grid, so the product does not present or promise hookups, power pedestals, or utility services. The product is not a luxury glamping or resort platform, and it does not add adjacent capabilities such as payments processing beyond what a reservation record requires, marketing automation, loyalty programs, or third-party channel distribution. No future-horizon requirements are currently accepted; anything not listed above is out of current scope.

2a. Product Interpretation and Delivery Boundary

The retreat itself is off-grid and located in Port Lavaca, TX, and there are exactly six tent and cabin sites in total. Those are hard facts about the place, and the product must reflect them truthfully rather than implying a larger or more serviced campground.

Delivery is first-party: the application owns the public pages, the booking flow, and the manager's reservation view. Identity is application-owned. A Guest establishes their own access through self-service enrollment before completing a durable booking, and returns through verification to resume protected booking continuity. The Campsite Owner/Manager does not self-enroll publicly; manager access is established by invitation or provisioning before protected reservation management is reachable. The Landing, Sites, Availability, Sign Up and Login surfaces are anonymously reachable; Booking and Reservations are protected.

Everything described in this document is current. There is no accepted future phase, and no capability should be built on the assumption of one.

2b. Source Content Inventory

Not applicable. No reference directive with content_source authority was supplied.

2c. Page Content and Component Coverage

Landing

• Information and state: Anonymous first impression of Bulls Bayou Retreat. Explains the off-grid setting in Port Lavaca, TX, the six tent and cabin sites, and the character of the place. No identity required.
• Primary actions: Proceed to check availability; proceed to see the six sites; proceed to booking.
• Supporting actions: Navigate to Sign Up or Login; navigate to Sites and Availability.
• Domain entities: Retreat (name, location, off-grid character), Site (six total, tent or cabin), availability signal per site.
• Component responsibilities: Full-bleed hero carrying the retreat's identity and the two entry plates; a ruled six-site ledger listing all six sites as numbered rows with number, name, type, sleeps, rate, availability indicator and a book link; the bayou/off-grid story block; a photo band; a booking strip; a header band with wordmark, navigation and the primary booking plate; a ruled ticker strip of off-grid facts.
• States: Loading — hero and ledger render with the retreat's structural bands in place while site data resolves. Empty — if site data is unavailable, the ledger shows a plain unavailable notice rather than blank rows. Success — all six sites listed with current availability indicators. Error — a site-data failure shows a retry affordance in the ledger region without breaking the hero or navigation. Recovery — retry re-requests site data and repopulates the ledger.

Sign Up

• Information and state: Anonymous self-service enrollment for a Guest who independently begins a booking journey. Explains that manager access is provisioned rather than publicly enrolled.
• Primary actions: Submit enrollment details to establish Guest access.
• Supporting actions: Navigate to Login for returning Guests.
• Domain entities: Guest identity (credential and contact details).
• Component responsibilities: Enrollment form with labeled fields and inline validation; submit plate; link to Login; a plain statement that manager access is by invitation or provisioning.
• States: Loading — submit plate shows in-progress state and prevents duplicate submission. Empty — form presented with no values entered. Success — access established and the Guest is carried into the booking journey they began. Error — invalid or already-registered details produce a specific inline message with the offending field identified. Recovery — the Guest corrects the field and resubmits without losing other entered values.

Login

• Component responsibilities: Credential form with labeled fields; submit plate; link to Sign Up; error region.
• States: Loading — submit plate shows in-progress state. Empty — form presented with no values entered. Success — identity verified and the actor is routed to the protected destination appropriate to their role. Error — incorrect credentials produce a plain message that does not disclose which field was wrong. Recovery — the actor retries; repeated failure keeps the form usable and preserves the entered identifier.

Sites

• Information and state: Browse destination for the six tent and cabin sites offered by Bulls Bayou Retreat. Anonymous. Each site is presented with its number, name, type (tent or cabin), sleeps count and nightly rate.
• Primary actions: Select a site to check its availability.
• Supporting actions: Navigate to Availability with a site preselected; navigate to Booking.
• Domain entities: Site (six total), site type, sleeps count, nightly rate, site diagram.
• Component responsibilities: A grid of badge-topped site cards, each with a distinct badge colour, a hand-drawn site diagram, and the site's identifying facts; a hand-drawn map of the six pads along the bayou as a hero-level illustration; a giant site-count numeral as page ornament.
• States: Loading — card grid renders with badge and diagram placeholders while site data resolves. Empty — if no site data is available, a plain notice replaces the grid. Success — all six sites shown with complete facts. Error — a data failure shows a retry affordance in the grid region. Recovery — retry repopulates the grid.

Availability

• States: Loading — table renders with its ruled structure while the check runs. Empty — before a range is chosen, the table prompts for a site and dates rather than showing a false result. Success — open and taken cells are shown for the requested range. Error — an invalid range (for example an end date before the start date) is rejected inline; a lookup failure shows a retry affordance. Recovery — the Guest adjusts the range or retries and the table refreshes.

Booking

• Information and state: Protected reservation completion destination for a chosen tent or cabin site and stay period. Requires verified Guest identity; a Guest who arrives without it is directed to establish or verify access before protected booking state is shown.

• States: Loading — the slip renders with its ruled structure while the selected site and range are revalidated. Empty — arriving without a selected site or range directs the Guest back to Availability rather than showing an empty slip. Success — the reservation is recorded and the Guest receives a confirmation slip for the specific site and stay period. Error — if the site is no longer open for the requested range, the Guest is told plainly and offered the next step; a submission failure preserves the entered selection for retry. Recovery — the Guest reselects an open site or range, or retries the confirmation, without re-entering everything.

Reservations

• Domain entities: Reservation, Site (six total), Guest, allocation state per site per day.
• Component responsibilities: A six-row by fourteen-day ruled allocation grid of square plates, one row per site, colour-coded by site type, with booked and open states distinguishable at a glance; a dense ruled ledger below with one row per booking and a colour-coded site column.
• States: Loading — the allocation grid and ledger render with their ruled structure while reservation data resolves. Empty — with no bookings, the grid shows all sites open and the ledger shows a plain no-bookings notice. Success — the fortnight's allocation and the full booking ledger are readable in one pass. Error — a data failure shows a retry affordance in the affected region without collapsing the other. Recovery — retry repopulates the grid and ledger.

4. User Personas

Guest

Product context. A prospective camper who wants to stay at Bulls Bayou Retreat, an off-grid campsite in Port Lavaca, TX with six tent and cabin sites. They arrive curious and often on a phone with a weak signal, so the path from interest to a confirmed reservation has to be short and unambiguous.

Primary goal. A confirmed reservation for a specific site and stay period.

Distinct accepted responsibilities. The Guest browses the six tent and cabin sites, checks a selected site against a requested date range, and completes a booking for the chosen site and stay period. The Guest also establishes their own access before completing a durable booking, and verifies their identity on return to resume protected booking continuity. This is the only persona that initiates a reservation; the operator never books on the Guest's behalf in the accepted scope.

Relevant inputs and decisions. Which of the six sites to pursue (tent or cabin), what date range to request, whether the returned availability makes the stay possible, and whether to confirm the reservation for that site and period.

Interactions with other accepted participants. The Guest's confirmation becomes the record the Campsite Owner/Manager reviews and allocates. The Guest's own observable outcome — the confirmation slip for a specific site and stay period — is the counterpart to the operator's allocation view.

Observable success. A recorded reservation for a specific site and stay period, with a confirmation slip showing site, dates, nights and total, and the ability to return and reach that booking after verifying identity.

Campsite Owner/Manager

Product context. The operator of Bulls Bayou Retreat, responsible for the six tent and cabin sites. They need the booking system to accept and track reservations across those six sites so that the campground's record matches reality.

Primary goal. An accurate, up-to-date reservation record for the campground.

Distinct accepted responsibilities. The operator reviews incoming bookings and reads site allocation across the coming period so that each site is correctly allocated. The operator's access is established by invitation or provisioning rather than public enrollment, and they verify their identity on return to reach protected reservation management. This is the only persona with access to the full booking ledger and the allocation view; the Guest never sees other Guests' bookings.

Relevant inputs and decisions. Which bookings are incoming, which site each booking occupies, and whether the allocation across the six sites is correct for the coming fortnight.

Interactions with other accepted participants. The operator's record is populated by Guest reservations. The operator's observable outcome — a readable allocation and ledger — is the counterpart to the Guest's confirmation.

Observable success. A fortnight's allocation across the six sites readable in one pass, and a booking ledger in which every reservation is correctly attributed to its site and stay period.

5. Core User Flows

Flow 1 — Guest discovers the retreat and browses the six sites

1. The Guest opens the Landing surface anonymously. The retreat's name, its Port Lavaca, TX location, its off-grid character, and its six tent and cabin sites are presented.
2. The Guest reads the six-site ledger, which lists all six sites as numbered rows with number, name, type, sleeps, rate and a current availability indicator.
3. The Guest selects the option to see the six sites and arrives at the Sites surface.
4. The Sites surface shows a grid of badge-topped cards, one per site, each with its type, sleeps count and nightly rate, alongside a hand-drawn map of the six pads along the bayou.
5. The Guest picks a site — for example a tent site — and proceeds to check its availability.
6. If site data fails to load at any point, a plain notice and retry are shown in the affected region; the Guest retries and the listing repopulates.

Flow 2 — Guest checks availability for a site and date range

1. The Guest arrives at the Availability surface with a site selected from the Sites surface, or selects one here.
2. The Guest enters a requested date range using the square date plates.
3. The Guest runs the check. The ruled availability table shows the requested range against the selected site, with open and taken dates distinguishable.
4. If the range is invalid — for example an end date before the start date — it is rejected inline and the Guest corrects it.
5. If the lookup fails, a retry affordance is shown and the Guest reruns the check.
6. For an open site and range, the Guest proceeds to Booking. If the site is taken for the requested range, the Guest changes the site or the dates and reruns the check.

Flow 3 — Guest establishes access and completes a reservation

1. The Guest arrives at the Booking surface with a chosen tent or cabin site and stay period. Because Booking is protected, protected booking state is not shown until identity is established.
2. The Guest is directed to establish access. On the Sign Up surface they submit their enrollment details.
3. If the details are invalid or already registered, a specific inline message identifies the field; the Guest corrects it and resubmits without losing other entered values.
4. Access is established and the Guest is carried into the booking journey they began.
5. On the Booking surface the Guest reviews the reservation slip, which shows the selected site, dates, nights and total.
6. The Guest confirms the reservation. The reservation is recorded for that specific site and stay period and the Guest receives a confirmation slip.
7. If the site is no longer open for the requested range, the Guest is told plainly and offered the next step — returning to Availability to reselect. If submission fails, the entered selection is preserved and the Guest retries without re-entering everything.
8. The Guest keeps the confirmation slip. Their reservation now stands in the operator's record.

Flow 4 — Returning Guest resumes protected booking continuity

1. The Guest returns and opens the Login surface anonymously.
2. The Guest submits their credentials.
3. If the credentials are incorrect, a plain message is shown that does not disclose which field was wrong; the form stays usable and preserves the entered identifier so the Guest can retry.
4. Identity is verified and the Guest reaches their protected booking state, where they can resume or complete their booking.
5. If the Guest has no access yet, they move to Sign Up and follow Flow 3 from step 2.

Flow 5 — Campsite Owner/Manager gains access and reviews reservations

1. The operator's access is established by invitation or provisioning — not through public enrollment. If provisioning has not completed, protected reservation state is unreachable and the operator is directed to complete verification.
2. The operator opens the Login surface anonymously and submits their credentials.
3. If the credentials are incorrect, a plain message is shown and the operator retries without losing the entered identifier.
4. Identity is verified and the operator reaches the protected Reservations surface.
5. The operator reads the allocation grid first: six rows, one per site, across the next fourteen days, with booked and open states distinguishable at a glance and colour-coded by site type.
6. The operator scrolls to the ruled ledger below, where each booking is readable with its site, stay period and Guest.
7. If reservation data fails to load, a retry affordance is shown in the affected region without collapsing the other; the operator retries and the grid and ledger repopulate.
8. The operator now holds an accurate, up-to-date reservation record for the campground across all six sites.

6. Visuals Colors and Theme

Muse and headline. Aaron Draplin — thick-line field-guide honesty for an off-grid Texas bayou camp. The register is rugged, plain-spoken, salt-air, proud-of-this-place and slightly stubborn: a hand-painted sign at the gate, a laminated map on the office wall, and a booking form that just works. It is not luxury glamping and not a corporate resort.

Colour tokens (light mode).

Denim and mustard are available only inside illustrations and site badges, never in UI chrome. Body text pairs #1C1A17 on #EDE4D3 or #F7F1E4 (both well above 7:1). Orange on kraft is used only at 18px+ bold or as a filled button with #F7F1E4 text.

Typography.

• Headings: Alfa Slab One, all-caps, single weight, tight leading (0.92), letter-spacing 0.01em. Headlines are set as slabs of type, flush-left, stacked two or three lines deep, allowed to run the full column width.
• Body: Oswald 400.
• Eyebrow/label: Oswald 600, 13px, 0.14em tracking, uppercase, sitting above every headline and section as a ruled eyebrow (e.g. SITE 03 · TENT, OFF-GRID · PORT LAVACA, TX).
• Numerals: site numbers, rates and dates set in Alfa Slab One at display size and treated as ornament; numerals in tables set in Oswald 500 tabular at 20px.
• Scale: 1.333 modular. Hero display clamp(56px, 11vw, 132px). Section display clamp(36px, 6vw, 72px). Card title 28px. Body 18px / 1.6. Small print 15px.

Shape language. Chunky and hand-built. 3px ink borders on panels and cards — thick, deliberate rules, not hairlines. 4px radii on buttons and inputs, 8px on cards, hard square corners on badges and stamps. Ruled horizontal bands separate every section like a ledger. Badge and stamp motifs: circular site badges with a 3px outline, a halftone photo or flat icon inside, and the site number in Alfa Slab One. Buttons are rectangular with a 2px ink outline and a 3px offset solid shadow so they read as physical, pressable plates. Diagonal hazard-stripe tape (ink/orange) is used as a section divider and as the edge treatment on the booking confirmation slip — decoration only, never over text.

Spacing rhythm. 12-column grid, hard 24px gutter, 64px section padding (24px at 375px).

Imagery style. Documentary Gulf Coast photography treated as halftone or duotone (ink + kraft, or ink + cypress-green): a flat tent pad at dusk, an oak mottled with Spanish moss, a kayak on the bayou at first light, a fire ring, a cabin porch, a heron. Every photo is cropped hard and bled off at least one edge — no photo sits politely inside a rounded card. Thick-line vector icons throughout: tent, cabin, kayak, fish, fire, water drop, sun, mosquito (with a slash through it), compass. A hand-drawn site map of the six pads along the bayou is a hero-level illustration on the Sites page. No stock people smiling at a laptop, no gradient blobs, no 3D renders.

Forbidden. The generic indigo/blue-on-white SaaS template. Green-and-white "outdoor brand" template look with rounded photo cards and a leaf logo. Bootstrap blue or indigo buttons, gradients, or any blue-on-white SaaS chrome. Grids of identical hover-lift cards with soft drop shadows. Centred hero with headline, subtext, blue CTA and a gradient blob. Inter, Roboto, Poppins, Montserrat or any neutral geometric sans as the heading voice. Rounded-pill buttons and 24px+ radii. Stock photography of smiling people around a laptop or a glossy camper van. Any motion that bounces, floats or drifts.

7. Signature Design Concept

The gate sign, the register, and the slip.

The public entry is composed as a poster for this one place. A single duotone photograph of Bulls Bayou at first light — flat water, oak line, one tent silhouetted — fills the viewport at 100vh on desktop and 86vh on mobile. Over the left seven columns, a solid kraft-paper block (#EDE4D3, 92% opacity) is laid down as a physical panel with a 3px ink border, and the headline is set inside it in Alfa Slab One, all-caps, flush-left, at clamp(56px, 11vw, 132px), broken as three stacked lines:

SIX SITES. NO HOOKUPS. BIG SKY.

Beneath the headline, one 18px Oswald line: "Bulls Bayou Retreat — off-grid tent & cabin camping on the Texas Gulf Coast, Port Lavaca." Under that, a pair of plates side by side: a filled orange CHECK AVAILABILITY button and an outlined ink SEE THE 6 SITES button, both with the 3px offset shadow. Bottom-right of the hero, overlapping the photo edge, sits a circular cypress-green badge stamp reading EST. PORT LAVACA, TX · OFF-GRID with a tiny tent pictogram. Bottom-left, a thin ruled ticker strip crosses the full viewport width in ink with orange text, scrolling the off-grid facts. Nothing is centred, nothing floats.

The concept carries through the product as three recurring objects: the six-site ledger on the Landing page, where all six sites appear as full-width ruled rows — oversized slab numeral, site name, TENT or CABIN tag in cypress or orange, sleeps count, nightly rate, a live availability dot, and a BOOK plate — reading like a hand-kept campground register rather than a card grid; the badge-stamp system, where every site and the retreat itself gets a circular thick-outline badge with a pictogram and slab numeral; and the reservation slip, where the booking confirmation and the right-hand booking panel render as a physical kraft slip with a perforated dashed rule, hazard-stripe edge tape, a stamp, and a ruled table of site, dates, nights and total — the thing a Guest screenshots and keeps. On the manager side, the same language becomes the allocation strip: a six-row by fourteen-day ruled grid of square plates, one row per site, colour-coded by site type, orange for booked and kraft for open, so the whole campground's fortnight is readable in one look before scrolling to the ledger.

8. Interaction Model & Motion Direction

Interaction Model: Static Motion Tempo: restrained Hero Dimensionality: flat

Landing Hero Motion Brief

• Focal subject: the duotone first-light photograph of Bulls Bayou — flat water, oak line, one tent silhouetted — with the kraft-paper headline panel laid over its left seven columns and the cypress badge stamp overlapping the photo edge bottom-right.
• Input → transformation → outcome thesis: as the page loads, the ruled bands wipe in left-to-right over 180ms and the headline lines slide up 12px and settle; the ticker strip begins its slow constant 40s loop. The outcome is a composed poster — the retreat's identity, its off-grid facts and its two entry plates — fully readable and immediately actionable, with no element still in motion once the reveal completes.
• Motion vocabulary: restrained and mechanical. No bounce, no float. Ruled bands wipe left-to-right over 180ms; headline lines slide up 12px and settle; hover on a site card swaps the badge icon for a halftone site photo with a 120ms crossfade and rotates the card's stamp 2 degrees; buttons press down 2px onto their shadow on :active; date-cell selection snaps with no easing; the ticker under the header scrolls at a slow constant 40s loop and pauses on hover.
• Composed first frame: the hero photograph at full bleed, the kraft panel with its 3px ink border in place over the left seven columns, the three headline lines set flush-left, the single Oswald subline, the two plates side by side with their offset shadows, the badge stamp bottom-right, and the ruled ticker strip crossing the full width bottom-left. Nothing centred, nothing floating.
• Reduced-motion state: all reveals become instant, the ticker becomes a static wrapped row of off-grid facts, and the site-card hover becomes a plain border-colour change. The hero remains fully composed and every readable element and control stays whole and inside the viewport at 375px, 768px and 1280px.

9. Non-Functional Requirements

NFR-1 — Off-grid truthfulness (explicit) The product must present Bulls Bayou Retreat as off-grid. No surface may present, imply or promise hookups, power pedestals or utility services. Rationale: the campground is off-grid, and a Guest arriving with wrong expectations is a product failure.

NFR-2 — Location accuracy (explicit) The retreat's location must be presented as Port Lavaca, TX wherever the retreat is described. Rationale: explicit hard constraint in the source.

NFR-3 — Six-site capacity integrity (explicit) Exactly six tent and cabin sites exist in total. Every listing, availability check, booking and allocation read must reflect that number, and no seventh site may be created, selected, booked or allocated. Rationale: explicit hard constraint in the source.

NFR-4 — Durable reservation state (required_inference) Reservations, site allocation and availability must persist server-side so that a confirmed reservation remains bound to the correct Guest and the correct site and stay period across sessions, and so that the operator's allocation view reflects the same state the Guest sees. Rationale: a booking system whose confirmations do not survive a session change cannot deliver the accepted outcome for either persona.

NFR-5 — Protected-state isolation (required_inference) Protected booking state must be reachable only after identity is verified, and the operator's reservation ledger and allocation view must not be reachable by a Guest. Rationale: a reservation is a commitment bound to a specific participant, and the operator's record covers other Guests' bookings.

NFR-6 — Mobile-first legibility under weak signal (required_inference) The booking path must remain usable on a phone with a weak connection: readable text and controls stay whole and inside the viewport at 375px, 768px and 1280px, and no element covers any part of them. Rationale: the audience books from a boat ramp or a truck cab, and the creative direction explicitly requires that readable text and controls stay whole at every viewport.

NFR-7 — Accessible contrast and reduced motion (required_inference) Body text must meet the direction's stated contrast pairing (#1C1A17 on #EDE4D3 or #F7F1E4), orange on kraft must be reserved for 18px+ bold or filled buttons with #F7F1E4 text, and prefers-reduced-motion must produce a usable static arrangement. Rationale: the direction states these pairings and the reduced-motion behaviour as requirements.

10. Tech Stack

• Frontend: React, delivered as a responsive web application. The creative direction's layout, typography and motion requirements are implemented in the frontend.
• Backend: Python with FastAPI, providing the booking system's reservation, availability and allocation endpoints and enforcing the six-site capacity constraint.
• Storage: A relational database for durable reservation, site and identity records, supporting the availability and allocation reads the Availability and Reservations surfaces depend on.
• Containerization: Docker and docker-compose for local and deployment packaging.

No other technology choices were specified by the user. Kubernetes is not required by any accepted constraint and is therefore not included.

11. Assumptions and Constraints

Constraints (source-stated, binding).

• The campground is off-grid.
• The campground is located in Port Lavaca, TX.
• There are 6 tent and cabin sites in total, comprising tent sites and cabin sites.
• The site includes a full booking system for reserving campsites.

Assumptions (narrow, labeled).

• Assumption — Guest identity is application-owned. Guest self-service enrollment and returning verification are required so that a reservation stays bound to the correct Guest and can be resumed. This is a required inference from the accepted booking journey, not a source-stated account feature.
• Assumption — Manager access is provisioned, not self-enrolled. The Campsite Owner/Manager reaches protected reservation management through invitation or provisioning. This is a required inference; the source does not describe how the operator obtains access.
• Assumption — Booking and Reservations are protected; Landing, Sites, Availability, Sign Up and Login are anonymous. This follows from the accepted lifecycles: a reservation is a commitment bound to a participant, and the operator's ledger covers other Guests' bookings.
• Assumption — No payment processing is in scope. The source asks for a full booking system for reserving campsites and does not describe payment. The reservation record, confirmation slip and allocation view are the accepted outcomes.
• Assumption — No future phase is accepted. All requirements in this document are current.

Explicit exclusions.

• No hookups, power pedestals or utility services are presented or promised, because the campground is off-grid.
• No luxury glamping or corporate resort positioning.
• No adjacent capabilities such as marketing automation, loyalty programs, or third-party channel distribution.

12. Glossary

• Bulls Bayou Retreat — the off-grid campsite in Port Lavaca, TX that this product presents and books.

• Tent site — a site type at Bulls Bayou Retreat, presented with a TENT tag.
• Cabin site — a site type at Bulls Bayou Retreat, presented with a CABIN tag.
• Availability — the open or taken state of a specific site across a requested date range.
• Reservation — a recorded commitment binding a Guest to a specific site and stay period, with nights and total.
• Confirmation slip — the Guest-facing record of a completed reservation, showing site, dates, nights and total.
• Allocation — the operator's view of which site is booked or open across the coming period, read as a six-row by fourteen-day grid.
• Guest — a prospective camper who browses the six sites, checks availability, and completes a booking.
• Campsite Owner/Manager — the operator of Bulls Bayou Retreat, who reviews incoming bookings and maintains accurate allocation across the six sites.
• Off-grid — the retreat operates without hookups, power pedestals or utility services.
