Command palette (cmd+K) with fuzzy nav, ticket search, people lookup and action entries (new ticket, logout, show shortcuts). Opens from keyboard or user dropdown. Global keyboard shortcuts via a small useShortcut/useLeaderShortcut hook: `?` help overlay, `c` new ticket, `g d|t|m|n|s` leader nav. Tickets list: j/k cursor, Enter open, x toggle select. TicketDetail: `e` edit, `r` focus comment composer. All guarded against firing inside text fields. @mention autocomplete in the comment composer (MentionTextarea) with arrow-key nav and Tab/Enter insert. Rendered comments and audit log rewrite @username tokens to links pointing at that user's assignee filter; unknown usernames left as plain text. Mobile sweep: TicketDetail sidebar stacks below content on <md, Settings profile grid collapses to one column, admin tables get horizontal scroll with a 640px min width, CTI 3-column grid stacks vertically on <md, New ticket severity/assignee grid same. PWA: manifest.webmanifest, SVG icon, minimal network-first service worker for the app shell (never caches /api/*), registered in production builds only. Theme-color meta + manifest link in index.
