zeekayandHanzo Dev 7f56d30320 feat: WebGPU-first Three.js scene template with automatic WebGL2 fallback
Neon Reef: ONE WebGPURenderer construction picks the best backend the browser
actually has, so the same bundle is a WebGPU demo on Chrome/Edge and a WebGL2
demo everywhere else. TSL node materials push the vertex wave onto the GPU; 900
instanced shards draw in a single call.

Why this exists: static-SPA builders cannot ship a game. Proving hanzo.app can
meant finding what actually stopped it, and three things did:

  1. POST /v1/projects/:slug/deploy carries the entire build in ONE request body
     and the public edge caps a body at 4 MiB (measured: 4194304 accepted,
     4198400 gets the opaque fasthttp "Error when parsing request"). Godot emits
     a 43 MB engine wasm; Unity 22 MB + 5.7 MB of data. The artifact lane cannot
     express a game at all, so these ship through the release lane instead: stage
     to the object store, then POST /v1/sites/:slug/publish promotes it
     server-side with no body.

  2. Engine loaders emit NON-fingerprinted filenames (index.js, <name>.loader.js)
     and clients/sites.CacheControlFor only marks a content-hashed name
     immutable. A redeploy therefore leaves the CDN and the browser running the
     OLD loader against the NEW wasm. That is not a visible error: emscripten
     prints "still waiting on run dependencies" forever and the canvas stays
     300x150. Every template here fingerprints its own asset names so the case
     cannot recur.

  3. A cross-origin-isolated document (COEP: require-corp) BLOCKS a plain
     cross-origin script, so the shared a.hanzo.ai runtime needs
     crossorigin="anonymous" on exactly the pages that opt into isolation.
