/* ============================================================================
   Clearline visual reset — shell + components (#73 skin).
   Ported from the approved reference build
   (clearline-marketing/mockups/visual-reset-reference/app.css) and adapted to
   consume tokens.css. Load order on every reset page:
     <link rel="stylesheet" href="/assets/css/tokens.css">
     <link rel="stylesheet" href="/assets/css/reset-shell.css">
   Adds the #73 a11y/quality gates the reference mockup omitted (focus rings,
   44px touch targets, prefers-reduced-motion, coral hover/press).
