  /* OPTICAL WEIGHT (preview, 2026-10-06). A stroke thickens as type gets bigger,
     so one weight everywhere makes small headings look thin beside big ones.
     Adam saw the 52px service names read two weights lighter than the 94px
     hero. Measured Trust 3A stems: Light .056em, Regular .079em, Medium .110em.
     Rule: weight goes UP as size goes DOWN, aiming every heading at the hero's
     ~5px stroke at desktop size. 90px+ Light; 57-76px Regular; 44-52px Medium;
     under 40px is text scale and stays Regular. The 27.5M figure stays Regular
     on purpose: it is the one deliberately heavy moment. */
