Implement the first scene of the Portal presentation video (6 seconds):
- AnimatedLogo scales from 0 to 100% with spring animation
- Wallpaper background with zoom effect (1.2 → 1.0 scale)
- Bitcoin particle effects in the background
- Pulsing glow effect around the logo
- Audio integration: logo-whoosh at start, logo-reveal when logo appears
- Title "EINUNDZWANZIG" and subtitle "Das Portal" with staggered entrance
- Vignette overlay for cinematic depth
