Summary

• render the existing shared main menu as a full-screen root page on compact layouts while preserving the desktop sidebar
• use paired iOS-style push/pop motion: the child slides from the right while the parent shifts partially off the left edge
• add an interactive iOS-app edge-swipe that follows the finger, completes by distance or velocity, and snaps back when canceled
• reuse that gesture for chat/project navigation, Settings detail-to-menu, and Settings menu-to-home while keeping mobile web and Android unchanged
• apply the same paired transition when the compact main menu opens or closes the entire Settings surface
• add centralized mobile history for menu, chat, New Chat, and project-detail pages without changing URL schemes
• make compact Settings a full-screen menu with existing category routes pushed as detail pages; preserve desktop Settings
• unmount popped chats after transitions and disconnect local streaming without canceling server-side processing
• add focused mobile history, Settings history, response-lifecycle, and swipe-decision tests
• update the mobile navigation plan with implementation status, gesture behavior, and the unsent-draft behavior

Validation

• bun test: 96 passing
• bun run typecheck
• bun run lint: no errors; 12 existing warnings
• bun run build
• Prettier check
• git diff --check

Remaining hands-on validation

• compact mobile-web layout, paired animations, and browser back/forward
• compact Settings menu/detail behavior across representative viewports
• iOS and Android suspend/resume and fresh launch
• navigation away from and back to an actively generating chat
• physical-iPhone swipe tracking, velocity/distance completion, cancellation, and vertical-scroll rejection

The iOS edge-swipe implementation is complete in code but intentionally remains subject to physical-device feel validation.
