═══════════════════════════════════════
REDUCED MOTION
═══════════════════════════════════════
prefers-reduced-motion: reduce → hide video; show poster as cover background-image on .hero__media; crush all animation/transition durations to 0.01ms

═══════════════════════════════════════
SHORT-HEIGHT COMPRESS (max-height: 640px)
═══════════════════════════════════════
Tighter nav padding; smaller H1 (clamp(36px,7vw,64px)); smaller form margins/gaps; thinner buttons; smaller legal (11px); tighter mobile menu

═══════════════════════════════════════
MOTION SUMMARY (what animates)
═══════════════════════════════════════
1. Background video continuous loop (primary presence)
2. Hover color/background transitions at 0.25s ease on links, CTAs, buttons, input border
3. Hamburger ↔ X morph 0.45s premium ease
4. Mobile menu circular clip-path expand 0.7s premium ease + opacity 0.45s
5. Mobile menu items staggered fade/slide-up with 70ms index delay
NO entrance animation on desktop panel. NO floating badges over video. NO cards, pills, glow, purple, or multi-shadow chrome. Sharp rects only. Aesthetic: black / white / translucent white glass, terminal-mono UI over cinematic face video.

═══════════════════════════════════════
STACK / IMPLEMENTATION NOTES
═══════════════════════════════════════
React + plain CSS (or equivalent). No Tailwind utility look required — custom properties as above. Form action="#" method="post" but preventDefault. Page is the hero only.
