/* yz-app-nav — shared mobile in-app navigation (Phase 1: doctor/admin/home).
   RTL right-side drawer + top-right hamburger trigger. Scoped under #yznav-root / .yznav-*
   so it never touches page styles. iOS/Android PWA safe-area aware. Sits above
   page chrome but below real page modals (root z 9998 < confirm/loading 9999+,
   toasts 11000) and also auto-hides while a full-screen page modal is open. */
