   Source of truth: docs/BRAND_DESIGN_PLAN.md §3; the home page is the owner-approved
   preview docs/_design/brand-hero/src.html, moved here. Rules that are law here:
   · every colour is a token in the two blocks below; no raw colour anywhere else;
   · three colour roles never swap: LIGHT (gold of the mark — signature, key word,
     glow only), ACTION (the mark's leaf green — primary button, links, selection),
     INK (warm neutrals — paper by day, the mark's warm black by night);
   · only transform and opacity animate; nothing moves faster than the chat seal;
   · Persian is never letter-spaced. */
