/*
  Stoop shared chassis — ported from peregrine's site/styles.css grammar
  (topbar, eyebrow/panel-label, truth-badge, hairline cards, fleet-table,
  buttons, focus states) with the accent swapped to Stoop's ice-cyan per
  docs/DESIGN.md. PASS/BLOCK semantics are untouched (still green/red);
  violet appears only in the footer lockup. No border-radius except the
  two deliberate exceptions noted inline — square hairline chrome is the
  house style, not an oversight.

  Loaded by site/index.html and site/lab/index.html as a <link>, same-origin,
  no external requests (system font stacks only — see docs/DESIGN.md and the
  Lab page's self-contained contract).
