/* Landing page. Scoped to body.home so the legal pages keep style.css as
   it is. The tokens mirror ProteinScannerCore/Tokens.swift ("Linen",
   PIVOT.md Phase 0): warm cream ground, warm near-black ink, white cards
   that lift off the cream, one plum accent. Light only; the face has no
   dark mode, so the dark tokens in style.css are overridden here. */
