# Project Context for AI Agents
|
|
|
|
_This file contains critical rules and patterns that AI agents must follow when implementing code in this project. Focus on unobvious details that agents might otherwise miss._
|

|
|
## Project overview
|
|
|
|
**Grateful Journal** — A minimal, private-first gratitude journaling web app. Three main pages (Write, History/calendar, Settings/profile) plus Google auth. No feeds or algorithms; privacy by design with client-side encryption; daily use, even one sentence.

## Critical implementation rules
|
|
|
|
### Frontend
|
|
|
|
- **Colour palette (Coolors):** Use CSS variables from `src/index.css`. Primary green `#1be62c`, background soft `#f1eee1`, surface `#ffffff`, accent light `#cff2dc`, accent bright `#c3fd2f`. Do not introduce new palette colours without reason.
|
|
- **Layout:** Responsive for all screens. Breakpoints: `--bp-sm` 480px, `--bp-md` 768px, `--bp-lg` 1024px, `--bp-xl` 1280px. On laptop (1024px+), page is single-screen 100vh — no vertical scroll; fonts and spacing scaled so content fits one viewport.
|
|
- **Touch targets:** Minimum 44px (`--touch-min`) on interactive elements for small screens.
|
|
- **Safe areas:** Use `env(safe-area-inset-*)` for padding where the app can sit under notches or system UI. Viewport meta includes `viewport-fit=cover`.
|
|
- **Structure:** Main app layout: page container → header + main content + fixed `BottomNav`. Content max-width `min(680px, 100%)` (or `--content-max` 720px where appropriate).
|
|
|
|
### Backend (when implemented)
|
|
|
|
- **Framework:** FastAPI. APIs in Python only.
|
|
- **Modularity:** Separate file per route. Each feature (users, entries) has its own router module.
|
|
- **Database:** MongoDB. Setup instructions below.
|
|
- **Port:** 8001 (backend); 8000 (frontend). CORS configured between them.
|
|
- **Authentication:** Relies on Firebase Google Auth token from frontend (passed in Authorization header).
|
|
|
|
### Conventions
|
|
|
|
- **Fonts:** Inter for UI, Playfair Display for headings/editorial, Lora for body/entry text. Loaded via Google Fonts in `index.html`.
|
|
- **Naming:** CSS uses BEM-like class names (e.g. `.journal-card`, `.journal-prompt`). Keep the same pattern for new components.
|
|
- **Build:** Fixing the current TypeScript/ESLint build errors is deferred to a later step; do not assume a clean build when adding features.
