   Babykare ERP — Mobile patches
   Additive breakpoints for <sm (< 640px) and <md (< 768px).
   Never overrides desktop behaviour.

   Sections:
     1. Layout — main padding for fixed bottom nav + safe areas
     2. Topbar — denser filter header on mobile
     3. Combobox triggers — 40px min-height for touch
     4. Tables — scrollable with min-width inside narrow cards
     5. Sidebar drawer — off-canvas overlay (desktop unaffected)
     6. PWA install button — bottom-fixed, mobile only
     7. Notifications drawer — slide-in panel from right
     8. Generic touch-target helpers
