   BML Tech — Marketing site design system  (REDESIGN PROPOSAL)
   Corporate palette unchanged: every token below is copied from the
   live site's own :root. No new hues introduced.

   Measured problems in the current styles.css this replaces:
     · 25 distinct font-size values across 94 declarations, despite a
       --text-* scale already being defined and then ignored
     · a full-screen loading screen that blocks first paint
     · 56 animated particles + 11 keyframe animations
     · flip-cards hiding real content behind a hover gimmick
