   Palette contrast note: #E48523 (accent) on #FAFAF8 (paper) measures
   ~2.6:1 — fails WCAG AA even at large-text size (needs 3:1), not just
   body text. Accent is therefore used ONLY as a fill (buttons, shapes,
   decorative rules), never as text/icon color on paper. Ink-on-accent
   (button text) measures ~6.9:1 — passes AA comfortably.
