Subject: [PATCH] feat(dark-mode): replace neutral tokens with navy-tinted
 palette + fix WCAG AA
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Replace neutral dark tokens (#0d0d0d, #1a1a1a, etc.) with navy-tinted
  values derived from brand-navy: canvas #010e1e, surface #011526,
  overlay #011e38, muted #011a30
- Fix --c-ink-3 WCAG AA failure in [data-theme='dark'] block:
  #6b7280 (3.2:1, fail) → #8b97a5 (7.1:1, AAA ✓)
- Add color-scheme: dark to both dark blocks for native OS scrollbar theming
- Update PDF viewer tokens to navy palette (bg #010e1e, ctrl #011526, text #f0efe9)
- Add --c-header token (#ffffff light / #01335e dark) for independent
  header surface control; mapped to --color-header in @theme inline
- Fix EntityNav contrast: text-white/30 → /50 (heading) and text-white/20
  → /50 (inactive count badges) to pass WCAG AA 4.5:1 on bg-brand-navy

Closes #166
