System Requirements Document for purple-start

1. Introduction

purple-start is a public website for an IT startup. Its purpose is to establish a credible, technically capable public presence, help prospective clients understand the startup’s offering, and provide a way for interested visitors to contact the company.

The website also supports the Startup Owner / Founder in maintaining the company’s public presentation over time through application-owned identity verification.

The active audience is limited to:

• Startup Owner / Founder
• Prospective Client / Visitor

2. System Overview

purple-start will be delivered as a custom website with four ordered first-party pages:

1. Landing
2. Services
3. Contact
4. Login

The public-facing experience presents the IT startup’s identity, service information, and contact path to anonymous visitors. The founder can use the Login page to establish identity on first use and verify identity on future visits in order to resume maintenance of the public site presentation.

Current Accepted Behavior

• Present purple-start as an IT startup company.
• Provide an anonymous public entry point.
• Let prospective clients browse service and company information.
• Let interested visitors contact the startup.
• Let the founder enroll on first use to manage public site content.
• Let the founder verify identity on return visits to resume content maintenance.

Current Exclusions

The current scope does not establish:

• A client portal.
• A project-management workspace.
• User accounts for prospective clients.
• Role-based permissions beyond the founder’s identity continuity for content maintenance.
• A service catalog with pricing, ordering, checkout, subscriptions, or payments.
• A support-ticketing system.
• A blog, news feed, careers area, or documentation center.
• External provider-owned contact, identity, or marketing surfaces.

2a. Product Interpretation and Delivery Boundary

purple-start is a founder-maintained marketing website for an IT startup. Visitors can arrive anonymously, understand the company’s public offering, and choose to make contact. The site should feel ambitious and technically credible while remaining practical for visitors evaluating whether to engage the startup.

The Landing, Services, and Contact pages are publicly accessible without sign-in. The Login page is also anonymously accessible so the founder can establish or verify identity before entering authenticated content-maintenance state within that page.

The current release is focused on presenting the startup and enabling inquiry. It does not establish broader operational software, client workspaces, or account-management capabilities.

4. User Personas

Startup Owner / Founder

Product context: The Startup Owner / Founder is responsible for establishing and maintaining purple-start’s public presence as an IT startup.

Primary goal: Present the startup credibly to prospective clients and keep the public website current as the business evolves.

Distinct accepted responsibilities:

• Establish founder identity during first use.
• Verify identity when returning to resume content maintenance.

• Makes the maintained public presentation available for visitors to view.

Observable success: The public site credibly represents the IT startup, the founder can resume content maintenance when needed, and inquiries reach the startup.

Persona provenance: required_inference. This role is required because the requester is building a website for their own IT startup and needs continuity to maintain the company’s public presentation.

Prospective Client / Visitor

Product context: The Prospective Client / Visitor arrives at purple-start to understand what the IT startup offers and decide whether it may fit their needs.

6. Visuals Colors and Theme

Muse: Gleb Kuznetsov
Headline: A luminous future-tech launchpad for purple-start

purple-start shall use a cinematic future-tech visual system that makes purple a defining brand signal. The website shall feel like a dark technical stage with one crafted digital object, high-contrast information overlays, and disciplined, practical public navigation.

Color Tokens

Blue and indigo shall not be used as primary action colors. The generic blue-on-white SaaS visual pattern is prohibited.

Typography

• Headings: Space Grotesk, weight 600–700.
  • Tight tracking: -0.045em.
  • Sentence case.
  • Oversized short lines.
• Body: IBM Plex Sans.
• System labels and metadata: IBM Plex Mono.
• Type scale: 112 / 76 / 52 / 32 / 22 / 18 / 16 px.
• Hero display: Clamp from 64 px to 112 px.

The implementation shall not use Inter, Roboto, Arial, Helvetica, Open Sans, Lato, or Poppins.

Surface and Shape Language

• Use dark translucent instrument-pane surfaces.
• Use low-opacity violet-white one-pixel edge lines.
• Use crisp 12 px corners.
• Use occasional circular orbital paths.
• Avoid generic soft cards, rounded consumer-app pills, and excessive frosted-glass treatments.
• Each panel should feel pinned into a technical field through labels, coordinates, technical lines, or a purposeful status indicator.

Layout

• Use a 12-column desktop grid.
• Include a narrow left rail for page coordinates and section markers.
• Alternate full-bleed dark visual fields with aligned information strips.
• Use a persistent left-edge section index:
  • 01 HOME
  • 02 SERVICES
  • 03 CONTACT
• Enlarge the active index number and emit a subtle purple line across the content grid.
• Use a slim top navigation rail with a purple status dot and numbered destinations.
• Use asymmetric service composition rather than equal-sized card grids.
• Use a command-console composition on Contact.
• Use a compact dark authentication module on Login rather than a separate generic white authentication screen.

Imagery

• Create one bespoke abstract 3D network object:
  • Faceted translucent purple core.
  • Fine luminous connection lines.
  • Suggests infrastructure, systems, and scalable software.
• Support the object with sparse interface schematics and service-capability diagrams.
• Use real product or work imagery only when available.
• Do not use stock team imagery, handshake photography, gradient blobs, floating pastel shapes, or flat clip art.

7. Signature Design Concept

The Landing page will open as a viewport-tall dark command field rather than a conventional centered SaaS hero.

A massive two-line Space Grotesk statement, BUILD WHAT’S / NEXT., occupies the left seven columns. A vertical acid-lime #DFFF45 coordinate strip interrupts the headline field. The lower-left headline area contains the rectangular lime Start a project action, rendered as a precise command cutout with black IBM Plex Mono text such as INITIATE_PROJECT →.

The right five columns contain a single translucent purple WebGL infrastructure core inside a thin-lined orbital frame. The object intentionally extends beyond the top and bottom bounds of the viewport. A small glass-black capability panel overlays its lower edge and presents SOFTWARE, CLOUD, and AUTOMATION.

This composition only presents accepted content and routes visitors to Contact when they choose to start a project.

8. Interaction Model & Motion Direction

Interaction Model: Animated
Motion Tempo: cinematic
Hero Dimensionality: webgl

Landing Hero Motion Brief

Focal subject: A bespoke faceted translucent purple infrastructure core held by fine luminous connection lines inside an orbital frame.

Input → transformation → outcome thesis: When the visitor arrives at Landing, the startup’s abstract infrastructure core slowly orbits within the technical field, catches moving violet light, and reveals the company’s capability labels—SOFTWARE, CLOUD, and AUTOMATION—as a visually coherent expression of scalable IT work. The outcome is a clear public entry point with visible routes to Services and Contact.

Motion vocabulary:

• Slow orbital movement around the purple core.
• Moving violet-light catch across faceted surfaces.
• Thin data paths tracing in during initial load.
• Subtle 8–12 px depth shifts in panels on pointer movement.
• Functional navigation and control hover feedback at 180 ms.
• No decorative particles or movement that impairs readability.

Composed first frame:

• The black-violet field is already visible.
• BUILD WHAT’S / NEXT. is readable
