/* ── 3dB Labs typography ───────────────────────────────────────
   Three-typeface system:
   · Inter — the workhorse. H2s are Inter Light 300 at 48px,
     sentence case. Subheads Inter Semibold 600. Body 15–16px/1.7.
   · Venera — display accent, used sparingly: hero headline,
     product names, brand stamps/lockups, tiny uppercase labels.
     ALWAYS uppercase + word-spacing 0.2em. Never body copy.
   · IBM Plex Mono — technical labels, data callouts, HUD captions.
