Document Reader

**Overview**
- Name: Document Reader
- Type: Chrome extension (Manifest V3)
- Purpose: Fast, privacy-friendly reader for PDFs with dark mode, TTS, and AI chat
- Works fully offline; no site access or tracking

**Short Description**
- Read and switch PDFs with dark mode, zoom, and offline TTS. Optional local AI chat for quick explanations.

**Key Features**

- Dark mode: Inverts page for comfortable reading without grayscale image corruption
- TTS: Read aloud current page with pause/resume and sentence navigation
- Quick switching: Visible "Open Document" buttons
- AI chat: Local WebAssembly model for page summaries and Q&A (no cloud calls)
- Lightweight UI: Sidebar controls, toolbar with zoom and view toggles

**How It Works**
- Uses pdf.js for rendering and a local pdf.worker to avoid CORS issues
- Applies tuned canvas transform in dark mode so the page is dark while diagrams remain readable
- Extracts page text to provide AI chat context locally via WebAssembly
- Saves basic settings (theme, TTS speed/voice, zoom) locally

**Permissions And CSP**
- No host permissions; the extension does not read websites by default
- Background service worker only to bootstrap the UI
