   AEQUARA · aeq-chrome.css — the ONE static-site chrome module
   2026-06-10 · chrome-unification (judge findings DC-3/DC-4/
   CV-03/CV-07/A11Y-06)
   ------------------------------------------------------------
   Canonical header + footer for every static HTML page under
   public/. Mirrors the React stack exactly:
     · nav    = /platform pf-nav lockup (circled-A mark + Fraunces
                wordmark) with links Decide · Tools · Trust ·
                Pricing · Platform and ONE persistent CTA
                "Try a tool free →" → /tools-v2
     · footer = static twin of app/_components/SiteFooter.tsx
                (same sf- classes, same 5-column IA, same blurb),
                light bone ground.
   Plain <nav aria-label="Main"> with plain links — no
   role=tablist/tab (A11Y-06). Current page gets
   aria-current="page" + bronze-deep underline.

   Self-contained: every var() carries a literal fallback so the
   module renders identically on token-less pages (merch). Ink
   text colours are LITERALS (not var(--aeq-fg)) so no legacy
   dark-ground token re-flip can invert them.
