		TimeTrackly
		===========

		ARCHITECTURE OVERVIEW:
		This is a single-page application (SPA) for local time tracking. It operates
		entirely in the browser with a local Node.js server providing data persistence.

		DESIGN PHILOSOPHY - Single-User, Local-First:
		- No authentication or user accounts
		- All data stored locally in JSON files
		- Complete privacy (no external network requests except CDNs)
		- Survives browser/system restarts via server-side state persistence

		MODULAR STRUCTURE:
		The application uses ES6 modules for clean separation of concerns:
		- app.js: Main orchestrator, initializes everything
		- state.js: Centralized state management
		- api.js: Server communication layer
		- ui.js: DOM manipulation and user interactions
		- reports.js: Chart generation and analytics
		- utils.js: Shared utility functions
		- constants.js: Configuration values

		UI ORGANIZATION:
		The interface uses collapsible sections to reduce visual clutter:
		- Start New Timer: Collapsed by default (indigo background)
		- Active Timers: Expanded by default (green background)
		- Data Export: Collapsed by default (gray background)
		All sections have smooth animations with rotating chevron icons.

		NOTES FEATURE:
		Each timer includes a Notes button that opens a floating modal dialog:
		- Click Notes button on any timer row
		- Modal displays "Notes for <Task Name>"
		- Explicit Save button required (or cancel/ESC to discard)
		- Close with: Save button, Cancel, ESC key, or click backdrop
		- Notes persist when saved, included in CSV exports
		- Empty notes stored as empty strings

		EXTERNAL DEPENDENCIES (CDN):
		- Tailwind CSS: Utility-first CSS framework for styling
		- Chart.js: Canvas-based charts for reports
		- Google Fonts (Inter): Typography

		IMPACT OF CHANGES:
		- Changing script type from "module" will break ES6 imports
		- Removing/changing CDN URLs will break styling or charts
		- DOM element IDs are referenced in ui.js - changing them breaks functionality

		MAINTAINABILITY:
		- Keep this HTML minimal - business logic belongs in JS modules
		- New features should add modules, not inline scripts
		- DOM structure changes require corresponding updates in ui.js

		ES6 Module Entry Point
		======================
		CRITICAL: type="module" enables ES6 import/export syntax.

		Loading app.js kicks off the entire application:
		1. Loads all other modules via imports
		2. Fetches data from server
		3. Initializes UI
		4. Sets up event listeners

		IMPACT: Removing type="module" or changing src path breaks the entire app.
		The server must serve this with proper MIME type (application/javascript).
