/* unsealday — warm, light, flat "calm report card" theme, inherited from the
   sibling product (aiheardofyou) per spec: same DM Sans, same flat-card/
   pill-button/large-radius recipe, same palette STRUCTURE — but a genuinely
   different accent so the two read as siblings, not a reskin. Sealing wax
   is thematically apt for a "sealed message" product: a deep, cool burgundy
   instead of the sibling's warm terracotta. Colors painted explicitly (one
   committed light theme, no dark variant). */
