/*
  hero.css — Refactor (R2)
  Goals:
  - Clean, component-scoped styles (no page spacing rules)
  - Consistent gold/glass identity (matches catalog/reader)
  - Performance tiering (mobile/coarse pointer + reduced motion)

  Notes:
  - Hero is intended to be a reusable component.
  - Page-level spacing (margins above/below hero) should live in page-*.css.
