/* /ai-answers hub — the owner's "NEURAL" hero spec adapted (2026-10-09). Tokens, veil, warm/cool glass CTA,
   chevron features, hairline rule and the entrance timeline follow the spec; sizes scale with one unit (--u)
   mapped from a 1536×1024 artboard. Differences: the page scrolls on to the answer list, the site CardNav
   replaces the spec's own bar, and Inter's variable axis (400–700) carries the fractional weights. */
