A whole site for an invented Marylebone skin clinic in brass on near black: gold pollen slowly gathers into a ginkgo leaf beside the headline and lets go grain by grain as you scroll, then a treatments grid that lets in a warm light leak under the pointer, typographic practitioner cards, glass membership plans whose prices roll, a constellation of client notes, a four step first consultation, and a booking card.
Signature momentAbout three seconds in at scroll 0: 22,000 grains of gold pollen have gathered from a mist into a tilted ginkgo leaf with its veins open, lit by a soft shaft from the top right with out of focus discs behind it, beside the headline and the brass booking button.
22,000 particles (a third on phones) in two RGBA32F textures move on the GPU inside a Worker: curl noise drift and a spring (k 7) toward points sampled from a ginkgo, orchid, fern or leaf. Each grain’s spring ramps in over 2.4 s, so a mist along the light becomes a leaf with open veins in about three seconds.
Scrolling the 70svh pin releases each grain at its own moment and lets it rise back along the light at (minus 0.10, 0.22); scrolling back gathers it again. Changing the silhouette keeps the particles and gives them new targets, so the dust flows from one shape into the next.
Eight treatment cells let warm light in from above the pointer: three CSS gradients and 160 px of seeded grain painted in the Worker. The leak is capped per look so lit text keeps 4.7:1, and the cell’s text moves toward the ink as it brightens.
Three glass plans sit over a ginkgo engraving drawn as one SVG path. The toggle rolls nine digit columns forward one full turn over 0.9 s with a 60 ms stagger, and in Chromium the hovered plan refracts the engraving through a displacement map of up to 46 px.
Eight client notes are the bright stars among 40 on a Canvas 2D sky. Pointing within 180 px draws hairlines to three neighbours and a line of the note; a click flies the camera 700 ms to 1.6 times zoom and opens it, and every note is also a keyboard button.
Page, ink and accent drive every surface: muted text is walked to 4.8:1 on both grounds, button labels are picked by contrast, and the sky, glass and leaks are derived, so STRATA.set turns the whole site light or dark live. Nine looks, four of them light.

# Clinic Noir: build prompt
## Role
You are a senior creative front-end developer. Build one self-contained `index.html`: the whole site of {{BRAND_NAME}}, an invented skin and aesthetics clinic in a {{PLACE}} mews house, brass on near black, that passes for a real high end clinic when read. Gold pollen gathers slowly into one botanical silhouette in the hero (raw WebGL2 in a Worker) and lets go on scroll; treatment cells let a warm light leak in under the pointer; typographic practitioners; glass membership plans with rolling digits; client notes as a Canvas 2D constellation; first consultation steps; visit and booking; questions; footer. Calm, warm, expensive: space, one brass accent, real numbers; every colour derives from page, ink and accent.
Copy rules: no medical claims, no guaranteed results, no before and after language, no "cure", "fix" or "anti-aging"; say "consultation", "suitability", "talk through options". Injectables appear only as "Injectables consultation with a medical practitioner". Client notes speak of the experience and the staff, never results. No em or en dashes (ranges read "9:00 to 19:00"), sentence case, British spelling.
## Output contract
- One file: `<style>`, a classic head script, the body, one module; no images.
- Import map `{"imports":{"lenis":"https://cdn.jsdelivr.net/npm/lenis@1.3.27/dist/lenis.mjs"}}`; import Lenis in an idle callback after `load` (`lerp: 0.1, smoothWheel: true, autoRaf: false, anchors: true`, `lenis.raf(now)` in your loop), never under capture or reduced motion. No other libraries or hosts.
- Fonts: preconnect both Google hosts, one non-blocking link (`media="print" onload="this.media='all'"` plus `<noscript>`) for `family=EB+Garamond:wght@400;500&family=Be+Vietnam+Pro:wght@400;500&display=swap`. Metric matched fallbacks (size-adjust, ascent, descent; line gap 0): EB Garamond on Georgia 78.5/128.3/38%, DejaVu Serif 74/136.1/40.3%, Liberation Serif or Times New Roman 94.3/106.8/31.6%; Be Vietnam Pro on Arial, Liberation Sans or Arimo 110.5/90.5/24%, DejaVu Sans 96.5/103.6/27.5%, each listed after the web font.
