/* ──────────────────────────────────────────────────────────────────────────
   Mobile menu (slide-in drawer with push-content behavior)
   ──────────────────────────────────────────────────────────────────────────
   Breakpoint chosen as 840px:
   - sidebar is 220px; with ~600px of useful content the layout starts to crowd
     anywhere below ~820px. 840 gives a touch of slack and is a common
     tablet-portrait threshold.
   - Landscape phones (852+) deliberately fall on the desktop side. If that
     proves cramped in practice, bump to a larger value here.

   Orthogonal to the @media (max-width: 600px) rule above, which only adjusts
   .form-grid columns and shares no selectors with this block.

   Push, not overlay: when the drawer opens, #main-content translates right by
   the sidebar width with the same timing as the drawer slide-in. There is no
   scrim. The drawer closes via the X icon, Escape, or tapping any nav link.

   Deferred: full keyboard focus management (focus-trap inside the drawer,
   restore focus to the toggle on close). Basics are in: semantic <button>,
   aria-label, aria-expanded, Escape-to-close.
