The super-resolution export ran single-threaded because the site was not cross-origin isolated and the runtime had no SharedArrayBuffer to spread a tile over. nginx now sends COOP and COEP — on the document, and on the script responses a nested worker fetches, which Chromium checks the same way and blocks as `coep-frame-resource-needs-coep-header` without them — and the loader asks for `min(8, hardwareConcurrency)` threads whenever the page is isolated, falling back to one if the headers ever go missing. A worker script is also why the landing's QR image needed `crossOrigin`: COEP refuses a cross-origin image that did not opt in with CORS. The unpack was the other half. Each tile was clamped a channel at a time and painted whole, padded ring and all; it now writes straight into the Uint8ClampedArray, which clamps and rounds on assignment, and skips the ring rather than drawing it and clipping it away. 640x480 to 4096: 39.0s to 16.2s. 1000x750 to 4096: 89.6s to 30.9s. One 256px tile through the model: 6.8s to 1.8s. Measured on the wasm path — the test browser has no GPU adapter — so a WebGPU export, still per-tile inference, keeps its own times.
