* 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.

- Strict monotonic Go coverage gate (make test-coverage-check, 45% baseline)
run in CI; fixes ginkgo dropping all-but-one coverprofile across multiple
recursive roots, builds with -tags auth, and folds in the in-process
tests/e2e suite via --coverpkg.
- React UI e2e coverage (make test-ui-coverage: vite-plugin-istanbul + nyc,
nix-provided Chromium) plus e2e specs for 6 previously-untested pages, and a
UI coverage gate (make test-ui-coverage-check) with a small tolerance since
e2e line coverage jitters ~0.5pp run-to-run.
- pre-commit hook: lint + coverage on Go changes, Playwright e2e + UI coverage
gate on react-ui changes; install with make install-hooks.
- New Go handler tests (settings, branding), hermetic base64 download test.
- fix(ui): model editor reads vram_display (snake_case), so the VRAM estimate
renders again; covered by a regression test.
