/* HoT Affiliate — Apple-UI design system (approved mockup, HoT-orange accent).
   Canonical HoT brand tokens: ink #001519 · cream #F8F7F3 · orange #E09132
   Apple structure (SF Pro, soft-shadow rounded cards, pill nav/buttons, segmented
   controls, generous whitespace) on warm-tinted neutrals so it reads HoT, not the
   cold SaaS grey-blue reflex. */
