System Requirements Document for daily-planner-paper

1. Introduction

This document specifies daily-planner-paper, a printable daily planner designed as a digital product for online sale. It defines the required single-file HTML/CSS deliverable, its print and visual requirements, and the structure needed to make future undated and weekly variants straightforward to create.

The intended audience is the Digital planner buyer, who prints the planner and uses its paper planning areas to organize a day.

Success Criteria

The deliverable is successful when it is one clean HTML/CSS file with no JavaScript; presents as a paper planner rather than a webpage; is sized and styled for US Letter printing and PDF export; uses the shared cute wallpaper; and includes clearly commented, reusable CSS for colors, fonts, and icons.

2. System Overview

daily-planner-paper is a static, printable daily planner artifact. Its current product behavior is the buyer’s use of the printed planner; it is not an interactive web application. The deliverable is one HTML file containing its CSS, with no JavaScript. It uses the shared cute doodle wallpaper and is structured so the file can be duplicated to create undated and weekly versions later.

The current scope does not define specific daily-planner fields, time intervals, or named planning sections. The design must provide usable daily planning space without inventing a prescribed set of planner categories.

2a. Product Interpretation and Delivery Boundary

The product is a downloadable, print-oriented HTML document intended for online sale. The HTML file is the product artifact, not a web application or a hosted user workflow. The buyer opens or prints the file and uses the resulting paper planner. PDF-export styling is required; a separate PDF-generation service or automated export feature is not specified.

The current deliverable is a daily planner. Undated and weekly versions are future duplication targets, not additional current deliverables. No account, backend, database, or application interaction is required for the planner’s accepted use.

2c. Page Content and Component Coverage

Daily Planner Sheet

• Information and layout: One US Letter portrait sheet, 8.5 × 11 inches, composed as a printable paper planner. The page should read visually as a designed sheet of paper, not as a webpage or application screen. Provide a clear daily-planning area with writable space; exact field labels and planning categories are not prescribed.
• Primary action: The buyer prints the sheet or uses print-to-PDF to produce a PDF-style copy, then writes their daily plans on the paper.
• Supporting design elements: Use the shared cute doodle wallpaper as part of the planner design. Preserve legibility and writable space when placing the wallpaper; it must support the planner rather than obscure its planning areas.
• Entities: The planner sheet, its daily planning areas, the wallpaper asset, and the CSS design tokens.
• Component responsibilities: The HTML provides the sheet’s semantic content and reusable structure. Embedded CSS defines the print page, layout, typography, palette, wallpaper placement, and decorative details. CSS comments identify how to swap colors, fonts, and icons. CSS variables expose the color palette for easy reskinning.
• Print and export states: The sheet renders at the specified page size in print media and remains legible when printed or saved through a browser’s PDF workflow. Print styling should avoid webpage navigation, browser-like cards, or other application chrome.
• Loading and failure considerations: The file must remain a single clean HTML/CSS artifact with no JavaScript. Google Fonts and the wallpaper are external or referenced assets; if an asset cannot load, the sheet should retain readable text and usable planning space through appropriate font fallbacks and a non-obstructive wallpaper fallback. No runtime loading interface or recovery workflow is specified.
• Future duplication structure: Keep the daily sheet’s content and styles organized so a copy can be adapted into undated or weekly versions later. Those variants are not part of the current page content or acceptance scope.

3. Functional Requirements

1. As a Digital planner buyer, I should receive one clean HTML/CSS planner file with no JavaScript, so I can use the planner as a static digital product.
   Provenance: explicit.
   Lifecycle and access: The buyer obtains and opens the delivered file; no application account or interactive access is required. The observable result is a single HTML file containing the planner and its CSS, with no JavaScript. If an external visual asset or font is unavailable, the file still presents readable content using fallbacks. The buyer can continue by printing or saving through a browser’s PDF workflow.

2. As a Digital planner buyer, I should be able to print the daily planner on an 8.5 × 11-inch page with print-ready, 300-dpi-equivalent, PDF-export styling, so the output is suitable for paper use and digital-product distribution.
   Provenance: explicit.
   Lifecycle and access: The buyer opens the file and prints it or uses print-to-PDF. The observable result is a US Letter-sized planner sheet with legible text and usable writing areas. If browser or printer settings affect output, the buyer can use the browser’s print/PDF controls; the file itself must provide print-specific styling. “300-dpi-equivalent” is a print-quality presentation requirement, not a requirement to rasterize the HTML.

3. As a Digital planner buyer, I should see a paper-planner design rather than a webpage, so the printed result feels like a planner sheet.
   Provenance: explicit.
   Lifecycle and access: On opening or printing the file, the buyer sees a composed planner page without webpage navigation or application chrome. The observable result is a paper-oriented layout with clear daily planning space. If decorative styling competes with legibility, the planning areas and text remain usable. The buyer continues by writing on the printed sheet.

4. As a Digital planner buyer, I should receive a planner design that uses the shared cute wallpaper, so the supplied visual asset is part of the product.
   Provenance: explicit.
   Lifecycle and access: The wallpaper is incorporated into the planner sheet’s visual design. The observable result is a cute doodle aesthetic consistent with the supplied wallpaper. If the wallpaper asset is unavailable, the file remains readable and its planning areas remain usable; the asset must not be silently replaced with unrelated imagery. The buyer continues to use the sheet as a daily planner.

5. As a Digital planner buyer, I should see Google Fonts used with serif headers and clean sans-serif body text, so the planner has the requested typographic contrast.
   Provenance: explicit.
   Lifecycle and access: The file requests Google Fonts for the specified roles. The observable result is serif header typography and clean sans-serif body typography when fonts are available. If Google Fonts cannot load, suitable local serif and sans-serif fallbacks preserve hierarchy and readability. The buyer can continue to print or save the sheet.

6. As a Digital planner buyer, I should be able to reskin the planner’s color palette through CSS variables, so its colors are easy to change.
   Provenance: explicit.
   Lifecycle and access: The CSS exposes palette values as variables. A person editing the file can change those variables and observe the updated colors without needing to rewrite the planner’s layout. If a variable is changed to an unsuitable value, the editor can restore or adjust the documented variable values. No separate configuration interface is required.

7. As a Digital planner buyer, I should receive CSS comments that make colors, fonts, and icons easy to swap, so the file is understandable and adaptable.
   Provenance: explicit.
   Lifecycle and access: The CSS includes comments identifying the relevant color, font, and icon styling points. The observable result is a self-contained file whose intended customization points are discoverable in its source. If a customization is unclear, the comments and CSS organization provide the available guidance; no separate documentation product is required.

8. As a Digital planner buyer, I should receive a file structured for duplication into undated and weekly versions later, so the daily design can serve as a starting point for those future variants.
   Provenance: explicit.
   Lifecycle and access: The HTML and CSS are organized for copying and adaptation. The observable result is a coherent daily-planner source file that can be duplicated without first disentangling unrelated application code. Undated and weekly planner content is not required in the current deliverable; the buyer or creator can use the structure as a basis for future versions.

4. User Personas

Digital planner buyer

Provenance: required_inference, as identified in Planning Scope.

The Digital planner buyer obtains the digital product for personal paper use. Their primary goal is to organize a day using the planner’s writable areas. They open the supplied HTML file, print it or save it through a browser’s PDF workflow, and write on the resulting sheet. Their relevant decisions are how to use the available daily planning space and, if desired, whether to print or save a PDF. Their observable success is a legible US Letter planner sheet that incorporates the cute wallpaper and is usable for daily planning. No additional user roles or account requirements are specified.

5. Core User Flows

1. Print and use the daily planner

1. The Digital planner buyer obtains and opens the single HTML/CSS file.
2. The buyer sees the daily planner sheet, including its writable planning areas and the shared cute wallpaper.
3. The buyer chooses to print the sheet or use the browser’s print-to-PDF workflow.
4. The browser renders the page using the file’s US Letter print styling. Google Fonts are used when available; fallback serif and sans-serif fonts preserve the header/body distinction if they are unavailable.
5. The buyer receives a legible paper sheet or PDF-style output and writes their daily plans in the available areas.
6. If print settings or unavailable assets affect the result, the buyer can adjust browser print settings or rely on the file’s readable fallbacks; the planner remains a static file and does not require an application recovery flow.

2. Adapt the file for a future planner variant

1. The person adapting the planner opens a copy of the delivered HTML/CSS file.
2. They use the CSS comments to locate the palette variables and the font and icon styling points.
3. They change the CSS variables or duplicate and adapt the organized source structure.
4. The observable result is an editable copy that can serve as a starting point for an undated or weekly version.
5. Undated and weekly planner content is future work; this flow does not imply that those variants are included in the current deliverable.

6. Visuals Colors and Theme

The shared cute doodle wallpaper is the authoritative visual inspiration for the planner’s palette, typography mood, visual density, and decorative style. It is a warm, light paper-like field with hand-drawn black doodle outlines and small pastel accents: blush pink, soft blue, muted sage, warm yellow, and gentle peach. Its motifs include cute animals, flowers, hearts, stars, notes, and encouraging phrases. Use the wallpaper as requested without allowing its details to interfere with writing space or legibility.

The separate dark dashboard design-system catalogue is unrelated to this planner’s source-backed visual direction and is not applied.

• Palette:
  • Paper: #FFF9F1 — warm cream sheet.
  • Primary ink: #29231F — soft near-black for readable text and outlines.
  • Blush: #E9A6B0 — gentle pink accents.
  • Soft blue: #A9C4DF — secondary accent.
  • Muted sage: #A8B28A — botanical accent.
  • Warm yellow: #F0C66E — small highlight accent.
  • Peach: #E8B9A5 — supporting warm accent.
    These values are coherent design defaults derived from the supplied visual reference and must be exposed as CSS variables for easy reskinning.
• Typography: Use Google Fonts with a serif family for headers and a clean sans-serif family for body text. [Default — not specified by user] Suggested pairing: DM Serif Display for headers and Nunito Sans for body text, with appropriate local serif and sans-serif fallbacks.
• Type scale: [Default — not specified by user] Use a clear print hierarchy: prominent sheet title, compact section labels, and comfortably readable body labels and writing prompts. Avoid dense or tiny text.
• Shape language: [Default — not specified by user] Soft hand-drawn lines, lightly rounded note-like accents, and restrained doodle details that echo the wallpaper without making the sheet feel like a webpage.
• Spacing rhythm: [Default — not specified by user] Generous, consistent spacing around writable areas; keep decorative elements secondary and preserve practical print margins.
• Imagery: Use the shared cute doodle wallpaper. Do not substitute unrelated imagery.

7. Signature Design Concept

Compose the daily planner as a warm cream paper sheet with a clear, elegant serif title and clean sans-serif labels. Let the shared cute wallpaper provide the recognizable hand-drawn character, with its pastel doodles used as a gentle frame or restrained decorative presence around the writable planning areas. Keep the central planning space calm and open so the sheet remains practical to write on. The result should feel like a thoughtfully illustrated paper planner, not a web page or dashboard.

8. Interaction Model & Motion Direction

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

Landing Hero Motion Brief

The product is a static printable sheet, not an interactive landing page. Its first accepted page is the Daily Planner Sheet. The focal subject is the paper planner itself, with the shared cute doodle wallpaper providing its visual character. The input→transformation→outcome is: the buyer opens the HTML file → the browser renders the styled US Letter sheet → the buyer prints or saves a PDF-style copy and writes daily plans on it. Use no motion; present a composed, legible first frame that shows the sheet as paper. Reduced-motion behavior is identical because the design is static.

9. Non-Functional Requirements

1. Single-file delivery: Deliver one clean HTML/CSS file with no JavaScript. Provenance: explicit.
2. Print dimensions: Set the print page to 8.5 × 11 inches. Provenance: explicit.
3. Print quality and PDF styling: Provide print-ready, 300-dpi-equivalent presentation and PDF-export-style rendering. Provenance: explicit.
4. Typography: Use Google Fonts, with serif headers and clean sans-serif body text; provide readable fallbacks if external fonts are unavailable. The fallback behavior is a necessary resilience measure for the explicitly requested font use. Provenance: explicit for font roles; required_inference for fallback behavior.
5. Reskinning: Expose the color palette through CSS variables. Provenance: explicit.
6. Adaptability: Organize the file so it can be duplicated for future undated and weekly versions. Provenance: explicit.
7. Customization guidance: Comment the CSS to make colors, fonts, and icons easy to swap. Provenance: explicit.
8. Wallpaper use: Incorporate the shared cute wallpaper into the planner design while preserving readable text and usable writing space. Provenance: explicit for wallpaper use; required_inference for maintaining legibility and writing usability.

10. Tech Stack

• HTML and CSS: One self-contained HTML file with its CSS; no JavaScript. Provenance: explicit.
• Google Fonts: Use a serif family for headers and a clean sans-serif family for body text. Provenance: explicit.
• Print CSS: Use print-specific styling for the 8.5 × 11-inch page and PDF-export-style output. Provenance: explicit.
• Backend and database: The provisioned environment includes a shared FastAPI backend and MariaDB database. They are infrastructure inventory only and are not used by this static, single-file planner; no API, persistence, or database-backed product behavior is required.

11. Assumptions and Constraints

• The current deliverable is the daily planner only. Undated and weekly versions are future duplication targets, not current deliverables.
• The source does not prescribe specific daily-planner fields, time intervals, or named planning categories; the design must not imply that any particular set was requested.
• The shared cute wallpaper is a required visual asset. Its use must not compromise legibility or writable space.
• Google Fonts may require network access. Suitable local fallbacks preserve the requested serif-header and sans-serif-body distinction when the fonts cannot load.
• The planner is a static file. No account, backend workflow, JavaScript behavior, or automated PDF-generation service is specified.

12. Glossary

• Daily planner: The current printable sheet for organizing a day.
• CSS variable: A named CSS value used to make styling, such as the color palette, easier to change.
• Print-to-PDF: A browser print workflow that saves a rendered document as a PDF.
• 300-dpi-equivalent: The requested print-quality presentation target for the HTML planner; it does not require rasterizing the document.
