/* ==========================================================================
   Responsive / mobile (release-hardening follow-up, v1)

   One breakpoint (900px) covers every tested phone/tablet width (390,
   430, 768) with a single consistent behavior rather than a separate
   in-between tablet layout -- simpler to reason about and verify.
   Above 900px, nothing in this section changes desktop behavior.

   Strategy per the mobile-readiness requirements:
   - Sidebar becomes an off-canvas drawer (`.sidebar.open`, toggled by
     `.menu-toggle`, closed by the backdrop, Escape, or picking a nav
     item -- see base.html's inline script).
   - Every `table.data-table` scrolls horizontally *inside its own box*
     (the classic display:block-on-<table> trick) instead of the page
     itself overflowing sideways.
   - Multi-column grids (dashboard, field-grid, status strips, tile
     rows) collapse to a single column so nothing gets squeezed.
