# Render/drive the binary-editor and dialog-editor webview harnesses in headless Chromium as a regression
# suite (scripts/test-harness.sh). Each driver mounts the real webview bundle and asserts through PASS/FAIL
# gates - catching render/mount/CSP/layout regressions the node/jsdom vitest suites cannot see.
#
# Kept in its OWN job rather than the main "Build" gate so the Chromium download (~150MB) and the browser
# runs add no wall-clock to every other check. See the harness READMEs and docs/architecture.md.
