/* GRAYMARKET — app.css (shell). Tokens from mockup/v1/DESIGN.md §0–§5 + §9 USER FIXES, motion from §10.
   PAGE SCALE (LAW 50): every length is N × var(--u), N = css px at 1920 (mockup px × 1.148). --u = viewport / 1920
   (set in index.html from clientWidth), 0.75px below 1024. Type = USER FIX TYPE sizes at 1920, never below 12 px.
   BORDERS (LAW 56): the ONLY place border/outline is written. Route bodies use the .rule-* classes below and write
   ZERO border/outline declarations. Every hairline is max(1px, …) so it never vanishes at 1280–2560.
   ONE PAGE FRAME (USER FIX 1): main.frame owns the ground #23272D and the 34 / 32 gutters @1920 — route bodies never
   set max-width, side padding or a page background. */
