/* =========================================================================
   Platform hub (pages/platform.php)
   C's hero + checker, B's size map, A's spec sheet, in one visual language.
   Uses only style.css tokens, so dark mode follows [data-theme="dark"].

   Brand: --brand is the platform colour (inline). --hb-l / --hb-d are tones of
   it that pass WCAG AA as small text on light / dark panels; --hb is the one
   for the current theme. --hb-fill is for shapes and fills, --hb-on the text
   colour that reads on it; --hb-badge / --hb-badge-on are the number badges
   (PHP picks the brand or --hb-l so the digits keep 4.5:1).

   Scale (shared by every part):
     radii   cards var(--radius) · feature cards var(--radius-lg) · inner boxes,
             controls, logo, thumbnails var(--radius-sm) · chips + badges 999px ·
             tags + map frames 6px · shapes drawn inside thumbnails 3px
     type    h1 clamp(28–40) · h2 clamp(22–28) · card titles 17–18 · body 14 ·
             labels 11.5 uppercase .06em · meta 12.5
     space   sections 56px apart (40 on phones) · head → content 16px
