feat(site): structured landing sections with eyebrow headings

Give the home page a clear, professional information hierarchy:
- Add eyebrow labels + headings for Features, Live stats and Community
  sections using reusable, theme-aware .eyebrow / .section-title styles.
- Loosen the vertical rhythm (gap-8/10) so each block breathes.
- New messages resolve via the existing English fallback for all locales.
