feat: BenditaRed-inspired concepts adapted to creeer tokens

- Hero: subtle ink grid texture (radial-masked) + gold glow blob
- Hero kicker: small gold dot before the eyebrow
- Header: desktop anchor nav (Método/Disciplinas/La estratega) with
  scroll-elevation shadow; mobile keeps wordmark + CTA only
- Sections gain ids + scroll-mt-24 as anchor targets
- CTA: subtle hover lift, gated with motion-reduce

Concepts studied from ~/dev/BenditaRed (grid+glow hero background,
kicker-with-dot, scrolled navbar state, pill hover lift). Animated
stats were skipped — no real metrics from the owner to show.
