Adopt Space Grotesk font and cyan-on-black theme from odek POC

- Replace Outfit (5 static TTFs) with Space Grotesk variable font (300-700)
- tokens.css: cyan accent (#22d3ee), near-black bg (#050507), slate borders
- base.css: cyan selection, dark scrollbar, effect utilities (glow, grid,
  panel, noise), POC keyframes/animations (marquee, scanline, pulse-dot...)
- buttons/hero: route hardcoded old-palette colors through tokens
- README: updated structure listing
