fix: a11y (gold-deep token AA, Disciplinas ul/li, Cierre nav) + scaffold cleanup
- Add gold-deep #7A5F15 token (~5.97:1 on white, WCAG AA) for small-text eyebrows
- Apply text-gold-deep to 4 eyebrows (Hero, Disciplinas, ComoEmpezar, Estratega)
- Disciplinas: div grid → semantic ul/li for screen-reader consistency
- Cierre: wrap contact links in <nav aria-label="Contacto">
- Estratega: portrait gradient → Tailwind tokens (from-ink to-gold), drop inline hex
- Delete unused Geist fonts (app/fonts/, ~134KB)
- Replace default README with creeer README
- Tests: +2 structural (Disciplinas ul/li, Cierre nav aria-label)
