/* ---------- Buttons ---------- */
/* Button text is INK, not white — an accessibility fix, not a style choice.
   Recomputed 2026-07-17 (WCAG 2.x relative luminance), AA normal text = 4.5:1:
     white     on --cta-500 #EA6A1E → 3.19:1  ❌   (what this shipped as)
     white     on --cta-600 #C9540F → 4.41:1  ❌   (darkening does NOT fix it)
     --ink-900 on --cta-500 #EA6A1E → 5.72:1  ✅
   Consequence: because the text is now dark, HOVER MUST GO LIGHTER.
   Hovering to --cta-600 would drop ink to 4.14:1 and fail on hover only —
   the nastiest kind, since it looks fine until you interact with it.
     --ink-900 on --cta-400 #F5853F → 7.23:1  ✅
   Any mid-tone warm accent behaves this way. If the CTA hue changes, re-derive
   both — do not eyeball it. */
