    legal/               # Privacy policy, terms of service
    welcome/             # Welcome page (shown on install)

Key design decisions:

• IIFE module pattern (no ES modules, no bundler required)
• importScripts() in service worker for shared modules
• chrome.runtime.sendMessage for popup-to-background communication
• chrome.storage.local for all persistence
• All operations are local -- no external API calls
