/* =====================================================================
   Trayo Newsfeed — Design system v4
   Hard rules:
   - ONE accent color per theme (indigo dark, brand purple light).
   - Per-type tinting limited to a small uppercase eyebrow label.
   - No nested boxes. The card is one surface.
   - Single anatomy: chrome / anchor / angle / footer.
   - Type scale is fixed and deliberate (no ad-hoc font sizes).
