/* Native ~80% UI scale for the logged-in app (matches browser zoom 80%).
   Applied at the root so it behaves like real page zoom: layout reflows, fixed
   overlays cover the full screen, and breakpoints shift — so more fits on small
   laptops. Scoped to `body.area-app` (the /app + /admin shell; marketing/login
   stay 100%) and gated to pointer:fine desktops/laptops (phones/touch stay 100%).
   --app-zoom defaults to 1 (no-op) and is set to 0.8 only where the zoom applies,
   so full-height shells that divide by it — calc(100vh / var(--app-zoom)) — stay
   correct off the zoomed path. Tunable via --app-zoom. */
