/* =====================================================================
   Cadence — admin dashboard
   RESPONSIVE — every media query in the app lives here, away from the
   component rules. Breakpoints: sidebar collapses to a top bar under
   900px, tables stack into labelled cards under 640px, and dialogs /
   stat grids compact further under 640px / 560px. Also the touch and
   reduced-motion behaviours.
   ===================================================================== */

/* ---------- Under 900px: the sidebar becomes an off-canvas drawer ----------
   A hamburger in the pagehead (hidden on desktop) opens it. The drawer is
   always present and translated off-canvas; `.is-open` slides it in over a
   scrim. Clicking a nav item, the scrim, or pressing Escape closes it (wired
   in main.js). z-index: sidebar 60 > scrim 55 > pagehead 30, and well below
   the slide-over (100) / dialogs so overlays still cover the drawer.
   `minmax(0, 1fr)` rather than a bare `1fr` is load-bearing: a grid track
   defaults to a min-content MINIMUM, so fixed-width children would widen the
   single column past the viewport and drag `.main` out with it. */

/* ---------- Responsive tables — rows become stacked cards under 900px.
   The sidebar becomes a drawer at 900px, so the content column there is
   only ~600–850px wide — too narrow for the widest table (Users, ~1360px
   natural). Tables stay real tables only when the sidebar is visible; in
   the whole drawer zone they reflow to labelled cards instead of forcing
   horizontal panning. The JS tags every <td> with a data-label; on small
   screens the cell is relaid out as a label + value pair so the core
   workflows (grant, approve, claim, settle) stay one thumb away without
   horizontal panning. ---------- */
