Lumi AI.

Dental clinics in Romania lose bookings to unanswered phones during peak hours. The product: an AI receptionist that answers every call, day or night, and a site that has to sell that idea to two audiences in two languages without reading as two separate products.

Locale is chosen by hostname: trylumiai.ro serves Romanian, trylumiai.eu serves the Kurdish-language build (src/i18n.ts:14). That works for a human visitor whose browser already resolved a hostname, but a crawler indexing a single-page app sees whatever the server renders first, which on both domains was the same static shell. Search engines would have seen only one language, no matter which domain they crawled.

The centerpiece is a hand-written WebGL 1 fragment shader, no three.js. It runs fractal Brownian motion through a rotation matrix to kill the axis banding a naive FBM produces, layers two levels of domain warping on top, and displaces an SDF sphere radius with live microphone input, with the bass isolated as the first 12% of FFT bins (src/components/LumiOrb.tsx:41-79,243-269).

The other half of the challenge is the language fork. A custom Vite plugin forks dist/index-en.html at closeBundle (vite.config.ts:5-25), and Vercel serves the right static HTML per domain based on a Host header match (vercel.json). One build, two domains, two crawlable language variants, no server-side rendering framework needed.

The .eu build adds a fourth language: a self-hosted Rabar Sorani face reachable at the URL segment kd but shipping the correct ckb lang attribute (src/lib/language-routing.ts:4-11), and metric-overridden local fallback fonts to suppress the layout shift Arabic-script font swapping causes (src/index.css:18-43). A prebuild script fails the build if the public AI-readable docs drift from the source data they describe (scripts/check-public-facts.ts:60-65), so a stale claim cannot ship.
