* Curate the highlight.js build to ~29 languages (lib/core + the common set) instead of the full ~190-grammar default: -787 KB raw / -230 KB gz on the base bundle. * Code-split every route via React.lazy with a per-layout <Suspense> in App.jsx so the sidebar stays mounted on navigation. Initial entry chunk drops from 3194 KB raw / 887 KB gz to 397 KB / 122 KB (-87%). Warm chunks on sidebar hover/focus/touch via a preload registry so the click finds the chunk already in flight or cached. * Migrate Playwright coverage from istanbul (build-time counters) to native Chromium V8 coverage, with per-worker accumulation + conversion. Suite drops from 71s to 30s at 20 workers (~58%) at the non-instrumented floor. * Keep the coverage gate bundling-invariant: the coverage build inlines dynamic imports so every shipped source file lands in the denominator (otherwise untested page chunks silently drop out and inflate the percentage). Production builds stay code-split. * Add UI_TEST_WORKERS=N Makefile knob; tighten coverage tolerance to 0.8pp now that jitter sits near istanbul's ~0.5pp again.
