/* ============================================================================
   MrepPortal — Home/Index Sales Dashboard  ·  UX/UI redesign
   Scoped entirely to `.mrep-dash` (dashboard content) and `#mSalesFilterModal`
   (its filter popup). The app shell (sidebar/header) is never touched.

   Theming: LIGHT by default. DARK is opt-in via `html.theme-dark` (toggled by
   index.js). Every colour is driven by CSS custom properties so the toggle
   re-themes instantly; charts read their palette from JS and re-render.

   Responsiveness is "to the leaf level": fluid type/space via clamp(), CSS grid
   auto-fit/minmax, per-card container queries (with media-query fallback),
   grid→scroll on phones, and >=44px touch targets on coarse pointers.
