 ## Architecture
 Extension uses background service worker + sidepanel UI. Mobile apps (iOS/Android) wrap this in dual-WebView architecture with native bridges (IOSBridge.swift / AndroidBridge.kt).
 
 ## Conventions
 - Vanilla JS, no frameworks
 - kebab-case file names
 - Chrome Web Store zips go in `distros/` folder
+- Xcode project lives at `dev/apple/NostrKey.xcodeproj`
 - WCAG AA contrast, aria-labels, reduced-motion support
