Why
The C# Avalonia-on-WebAssembly build froze during analysis: wasm there is single-threaded (so the OpenCV work ran on the sole UI thread), interpreted, linked at
-O0, and boxed into a 256 MB heap. True multithreading in the browser needs cross-origin-isolation headers GitHub Pages cannot set. Web is the only target, so the app is rewritten as a plain web app that runs the same measurement pipeline off the main thread.What
web/: Vue 3 + TypeScript + Vite + Vuetify. The CV engine is ported 1:1 to TypeScript and runs in a Web Worker via OpenCV.js, so analysis never blocks the UI, needs no special headers, and is fast. Native HTML file/number inputs replace the whole Avalonia mobile-input workaround saga.TestData_2solid.pngfixture at the same tolerances (23 rings, ~0 skew, isotropy) via Vitest, plus Playwright over real scans (the card recovers ~23.6 px/mm; the two-scan flow completes on 35 MP scans without freezing).src/, the C# workflows, and the C#-only root tooling are deleted. Kept:web/, the coupon model (calibration_coupon.scad/.stl), andimg/.web-ci.ymlbuilds + unit-tests + e2e-tests on PRs and master;deploy-web.ymlpublishesweb/distto GitHub Pages on push to master (served at https://jaak0b.github.io/ScanNTune/). The e2e scan fixtures are stored in Git LFS.Verification
npm run buildclean, 60/60 Vitest pass, 3/3 Playwright e2e pass over the real scans.
