Fix: colour contrast issues across site

- CTA box btn-secondary: add !important to override global .btn-secondary
  (white text was being overridden by global color: #144784 !important)
- Article body links: #148a72 (3.9:1) -> #0b6b54 (5.2:1) — passes WCAG AA
- Pricing note text: #999 -> #6b7280 on white/light bg (2.6:1 -> 4.6:1)
- Card placeholder text: #999 -> #6b7280 on #f8f9fa (2.5:1 -> 4.6:1)
- Footer #ccc on #151f25 confirmed fine (9.5:1) — no change needed
