Fonts
Google Fonts:

family=Instrument+Serif:ital@0;1&family=Barlow:wght@300;400;500;600
Tailwind config adds:

font-heading → 'Instrument Serif', serif (always italic in use)
font-body → 'Barlow', sans-serif
Default border radius override: DEFAULT: "9999px" (so bare rounded → pill).

Liquid-glass utilities (exact CSS, in a <style> block)
Two variants — .liquid-glass (subtle, for nav/chips/cards) and .liquid-glass-strong (heavier blur, for primary CTA):

.liquid-glass {
background: rgba(255,255,255,0.01);
background-blend-mode: luminosity;
backdrop-filter: blur(4px);
-webkit-backdrop-filter: blur(4px);
border: none;
box-shadow: inset 0 1px 1px rgba(255,255,255,0.1);
position: relative;
overflow: hidden;
}
.liquid-glass::before {
content: "";
position: absolute; inset: 0;
border-radius: inherit;
padding: 1.4px;
background: linear-gradient(180deg,
rgba(255,255,255,0.45) 0%,
rgba(255,255,255,0.15) 20%,
rgba(255,255,255,0) 40%,
rgba(255,255,255,0) 60%,
rgba(255,255,255,0.15) 80%,
rgba(255,255,255,0.45) 100%);
-webkit-mask: linear-gradient(#fff 0 0) content-box, linear-gradient(#fff 0 0);
-webkit-mask-composite: xor;
mask-composite: exclude;
pointer-events: none;
}
.liquid-glass-strong { /* same but: */
backdrop-filter: blur(50px);
box-shadow: 4px 4px 4px rgba(0,0,0,0.05), inset 0 1px 1px rgba(255,255,255,0.15);
}
.liquid-glass-strong::before { /* same but 0.5 / 0.2 / 0 / 0 / 0.2 / 0.5 stops */ }
FadingVideo component (custom JS crossfade, no CSS transitions)
Wraps a <video autoPlay muted playsInline preload="auto"> starting at opacity: 0. Behavior:

FADE_MS = 500, FADE_OUT_LEAD = 0.55 seconds.
fadeTo(target, duration) uses requestAnimationFrame; reads current opacity from http://video.style.opacity so each new fade resumes from wherever the last one left off. Each call calls cancelAnimationFrame on the previous rAF id before starting.
On loadeddata: set opacity 0, play(), fadeTo(1).
On timeupdate: if fadingOutRef not set and duration - currentTime <= 0.55 and > 0, flip the ref and fadeTo(0).
On ended: set opacity 0; after setTimeout(100ms) reset currentTime = 0, play(), clear fadingOutRef, fadeTo(1).
loop attribute is OFF (we implement looping manually via ended).
Cleanup on unmount: cancel rAF, remove listeners.
Section 1 — Hero (full viewport, black bg)
Background video (120% width/height, top-aligned, centered horizontally — focal point is the top of frame):

Notes
All text white; no green, no gradient backgrounds.
No CSS transitions on the videos — fades must be rAF-driven per the FadingVideo spec.
Videos are full-bleed with no dark overlay; contrast comes from the liquid-glass chrome.
Framer Motion dev warnings about list keys can be suppressed with a console.error filter wrapper — they're benign.
The detailed prompt above captures every element, style, animation, video URL, and font to recreate the landing page exactly.
