/* ══════════════════════════════════════════════════════════════════════════
   MAD DESIGN SYSTEM  —  app/mad-ds.css   (Pass 2, 2026-09-29)

   One vocabulary for every screen. Loaded right after the base <style> in
   index.html, before every layer script, so it is the floor the app stands
   on. Everything here is namespaced `ds-` (plus a few id-scoped rules for the
   shared #sheet / #toasts chrome) so no later layer overrides it by accident,
   and it never has to fight one with !important.

   Built on the :root tokens in index.html (--bg --panel --line --txt --dim
   --faint --mad --mad2 --madDeep --madGlow --green --red --gold, --sp1..8,
   --e1..4, --mono --disp --head, --spring). RH mode (body.rh-mode, rh-tab.js)
   swaps --mad/--mad2/--madDeep/--madGlow to green; the tint tokens below are
   re-declared for it, so every component recolours with the chain.

   See DESIGN-SYSTEM.md for the catalogue.
