/* ─── Global UI density ───
   The platform renders too large at 100% browser zoom — users had to zoom out to ~75%
   for a clean view. Render the whole UI at compact density instead, so 100% browser
   zoom looks like the old 75%. Desktop-only (phones/tablets keep native sizing).

   This is THE single knob for platform-wide density — tune BOTH values together here,
   never per-page. Two compensations exist because CSS zoom does not scale viewport
   units or rect→style coordinate math:
   - viewport heights: use `calc(var(--sf-vh) * N)` instead of `Nvh` (plain vh only
     covers 1/zoom of the screen under root zoom);
   - JS that positions fixed elements from getBoundingClientRect() must divide the
     coordinates by `--sf-ui-zoom` (rects are visual px, style px are layout px). */
