   Bold / high-energy / dark charcoal + electric lime
   ---------------------------------------------------------
   Contrast notes (WCAG AA — measured):
   - Accent lime (#C8FF00) is used as TEXT only on dark
     surfaces (#0E0F11 / #15171A / #1C1F23). Lime-on-charcoal
     ≈ 16:1; on the lightest card (#1C1F23) still ≈ 14:1.
   - On the lime button, text is near-black (#0E0F11) →
     ≈ 16:1. Lime is NEVER used as small text on a light bg.
   - Body text #E7EAEC ≈ 14–16:1; muted text #AEB4B8 ≈ 7.9–9:1;
     error #FF6B6B ≈ 6.5:1; placeholder #7D8488 ≈ 4.7:1 —
     all pass AA for their text size.
