   Goal: drivers in the field can do walkaround / POD / view current job
   without pinch-zoom. Bottom-tab nav (instead of side nav), touch targets
   ≥ 44px (Apple HIG), tables collapse to cards, modals full-screen.

   Rules of thumb:
   - .mobile-only / .desktop-only utility classes for content swaps
   - .table-mobile-cards on a <table> turns its rows into stacked cards
   - .btn-mobile-primary makes a button big enough for a thumb in a glove
   - .body-has-bottom-nav adds bottom padding so the last row clears the nav
