The /launch landing page (bleeding-edge waitlist hero):
- Full-viewport WebGL node engine (src/lib/hero/nodeEngine.ts): 40k GPU particles
on a two-FBO GPUComputationRenderer running an 18s looping cinematic — particles
stream in from the screen edges, slam together and EXPLODE at center, reform into
a brain / graph constellation / neural lattice, dissolve back out, loop. Glowing
additive particles + UnrealBloom, fills the whole screen edge to edge.
- Key GPGPU fix: custom DataTexture shape targets read black in GPUComputationRenderer
(three.js #15882), so shape targets are computed PROCEDURALLY in-shader from the
per-particle seed. Position integrates raw per-frame velocity (Codrops pattern),
texel-center reference attribute.
- AmbientField (god-ray glow + parallax starfield), phantomBrain (deterministic
seed-from-identity memory graph), LandingHero/neuralFlow (WebGPU Cinema-storm
reuse + WebGL fallback, kept as alternates). Manifesto copy, seed input, email
capture. No em-dashes. SSR off + prerender for the WebGL route.
Waitlist backend (Supabase, owned data):
- supabase/migrations/0001_waitlist.sql (RLS-locked table, dedup), Edge Function
waitlist-join (CORS, validation, honeypot, dedup, Resend confirmation), setup doc.
Dashboard auth removed (reverts the launch-polish auth wall that 401'd the dashboard
against itself): mod.rs/state.rs/websocket.rs back to no-token, api.ts/websocket.ts/
+layout.svelte stripped of the token client. Pending-review UX + Memory PR gating kept.
Research/spec docs under docs/launch/. Frontend typechecks 0/0.
