/* THE VAULT · HOUSE SHEET · shared/vault-house.css
   One roof, many rooms: reset, tokens, top bar, saga shellbar,
   the wire, foot marks. Nothing editorial.
   THE CONTRACT: link this sheet before the page's own <style>.
   A page re-tints the house by restating tokens in its own :root
   AFTER the link; its block comes later, so it wins. Nobody edits
   this file to repaint one room. The house is gold; cyan belongs
   to Argentina 1990 alone, and those rooms restate --shell-accent
   and --shell-glow in their own blocks. Room-dialect aliases let
   watch / hear / reader migrate unmodified.
   DRIFT (audit 2026-08): where pages disagreed the portal won
   (.eyebrow .3em/.6rem, .foot 40px 22px 24px, .row-h span .58rem,
   .brand img 44px). Sheet eyebrow and title em are gold here; the
   portal re-tints them cyan itself. The shellbar is the
   homologated watch/hear body (reader's top:3px was drift); its
   cyan literals became the --shell-* props with gold defaults. */
