Verifying changes in this repo

Build & serve

npm ci                 # if node_modules is missing (vite: not found)
npm run build          # vite build → dist/
npm run preview -- --port 4173 --strictPort   # serve dist/ in the background

npm run dev (port 5173) also works for iterating without rebuilding.

Drive with Playwright

The repository's own Playwright works in web sessions—npm run test:interface and npx playwright test both launch—because .claude/hooks/session-start.sh links the browser revision the client expects to the Chromium the image carries. For driving the app outside the test suite, use that same build.

Chromium is pre-installed; do NOT run playwright install. Install playwright-core into a scratch dir and launch with:

chromium.launch({
  executablePath: "/opt/pw-browsers/chromium-1194/chrome-linux/chrome",
});

(The bare /opt/pw-browsers/chromium path is a directory, not the binary — glob for chromium-*/chrome-linux/chrome if the version bumped.)

Routes worth driving

• /#/en — landing page
• /#/en/story/{person_id} — person story (e.g. alan_turing)
• /#/{lang}/meta/{meta_story_id} — meta story (e.g. en/meta/computing_pioneers, de/meta/citizens_of_bamberg)

The meta story page has scroll-driven sections (timeline scroll-proxy, network scrollytelling), so drive them by scrolling the window, not by clicking. For the network section, wait for .network-svg:not(.hidden) (layout settles in the background), then scroll .mnet-steps .step elements into the 55%–75% viewport band to activate cards; .node.dim counts are a cheap assertion for highlight state.

Gotchas

• Map tiles/sprites (protomaps.github.io) may fail through the proxy — AJAXError: Failed to fetch console errors from the map are environmental, not a regression.
• Test both a desktop viewport and a narrow one (< 560px switches the network to compact sizing), and de alongside en for locale keys.
