/* aecre site system (Step 3 of the UI/UX pass, Oct 28, 2026).
   One shared stylesheet for pages rebuilt in the quiet-authority system. A page opts in with
   <link rel="stylesheet" href="/css/site.css?v=..."> and <body data-system="qa">, and then carries no page-wide inline CSS.
   Targets, enforced by _checks/check_system.py on every opted-in page:
     body copy 16 px or more (15 px floor for small print), no text under 12 px, buttons 44 px tall or more,
     every text color pair 4.5:1 or better, one sticky layer per screen size, no content hidden until scroll or hover.
   Font: Plus Jakarta Sans 400/500/600/700/800 plus 400 italic, loaded by the page from Google Fonts. */
