Marcel 4c57a2262f test(frontend): guard wasm shipping at build time, drop CI-fragile pixel test
The in-browser pixel-render fixture test was green locally but flaky in
CI: the real pdf.js worker could not fetch /pdfjs-wasm/ in the CI
Chromium container, so the CCITT canvas stayed blank (0 sampled pixels)
and failed the suite — green locally, red in CI, root cause not locally
reproducible. A flaky gate is worse than none.

This bug is a build/serve parity failure, so guard it deterministically
where it actually breaks: a postbuild assertion that jbig2.wasm and
openjpeg.wasm shipped into build/client/pdfjs-wasm/ (non-empty). It runs
after `npm run build` — including the Docker build stage — and fails the
build loudly if a future pdfjs bump makes the static-copy glob match
nothing. Combined with the getDocument(wasmUrl) unit guard and the
negative-path render test, the regression is covered without CI flake.

Addresses re-review: Tobias (no automated parity check), Sara (pixel
test not pinned). Render-decode correctness verified manually via
`node build` serving /pdfjs-wasm/jbig2.wasm as application/wasm.

sv

Everything you need to build a Svelte project, powered by sv.

Creating a project

If you're seeing this, you've probably already done this step. Congrats!

# create a new project in the current directory
npx sv create

# create a new project in my-app
npx sv create my-app

Developing

Once you've created a project and installed dependencies with npm install (or pnpm install or yarn), start a development server:

npm run dev

# or start the server and open the app in a new browser tab
npm run dev -- --open

Building

To create a production version of your app:

npm run build

You can preview the production build with npm run preview.

To deploy your app, you may need to install an adapter for your target environment.
