  2. Typography
  3. Layout helpers
  4. Header & navigation
  5. Buttons & links
  6. Hero & media

  Notes:
  - Keep section-specific rules grouped to avoid duplication.
  - Targeted overrides (eg. #submission-form .two-column) are placed near layout helpers.
  - Remove or consolidate duplicates found by searching for identical selectors.
