Redesign: "Warm Paper" visual system, real logo + webfont, polished pages

- Brand: replace 🌈-emoji placeholder with the real logo in header, hero
  and footer; embed the Apex Brush webfont locally (/public/fonts)
- Design system (global.css): warm paper palette, Fraunces + Hanken Grotesk,
  sticker buttons/cards, squiggle underlines, organic blobs, wave dividers,
  staggered load motion; wrap base/components in @layer so Tailwind
  utilities reliably override (fixes ignored padding/weight overrides)
- Home: new hero showcasing the logo, manifest, three pillars, Momente
  gallery (placeholder photos), stats band, projects, CTA
- New components: PageHeader, Wave, Decor
- Subpages: unified headers (Apex Brush eyebrow + Fraunces H1), blob badges,
  consistent CTA bands and chips; add real .prose styling (no Tailwind
  typography plugin installed)
- Fix datenschutz: font names Pacifico/Inter -> Fraunces/Hanken Grotesk
