Step 30 of v4.3 plan — Wave 7 Group D:
- voyage-playground-a11y.spec.mjs (3 tests): light + dark theme axe-core
scans (compared against baseline JSON, fails only on NEW or GROWN
violations) + pixel-diff smoke for SC1 (light + dark, 1280x900,
maxDiffPixelRatio=0.02).
- voyage-playground-network.spec.mjs (1 test): SC7 authoritative gate via
page.on('request') instrument — verifies zero external (http/https/ws)
requests during page load.
- playwright.config.mjs: snapshotPathTemplate routes to tests/e2e/snapshots/
(matches Step 31 expected_paths).
Baseline policy: HTML is FROZEN in Sesjon 6 (Wave 7 = verification, not
fix). Existing critical/serious WCAG violations (aria-hidden-focus +
color-contrast) recorded in tests/e2e/snapshots/a11y-baseline.json as
delta-baseline. Actual a11y fix deferred to v4.4.
Verify: npm run test:e2e -> 4 passed (3 a11y + 1 network).
