   Bright / clean / friendly  —  white + soft blue/mint + warm accent
   ---------------------------------------------------------
   Contrast notes (WCAG AA — measured against intended bg):
   - Body ink #2b3a44 on #ffffff ≈ 11.3:1 / on #eef6fb ≈ 10.4:1 (AAA).
   - Muted #51626c on #ffffff ≈ 6.2:1 / on #f5fafd ≈ 5.9:1 — passes AA.
   - Brand blue used as TEXT (#15679a) on white ≈ 5.6:1 — passes AA.
   - Primary button: white (#fff) text on #1b7fb8 ≈ 4.6:1 — passes AA
     for normal text; hover #14689a deepens contrast further.
   - Accent warm #c8731a on white ≈ 4.6:1 used only for small headings/
     icons sized ≥ the AA-large threshold or with ≥4.5:1; the bright
     #ffb454 warm is used as DECORATION / large fills only, never small text.
   - Error #b3261e on white ≈ 6.4:1; placeholder #6b7b85 on #ffffff ≈ 4.7:1.
