Public site Phase 10 evidence

Outcome

Repository hardening is complete. Chromium, Firefox, WebKit, and mobile journeys cover download, onboarding, search, integrations, community, navigation, and theme behavior. Axe reports no known serious or critical violations after light-theme contrast and mobile scroll-region fixes. Four visual baselines cover the primary surfaces.

The build validates unique metadata, canonical identity, required outputs, image alternatives, a 300 KiB HTML ceiling, 200 KiB JavaScript asset ceiling, and 200 KiB first-party JavaScript total; current first-party output is about 102 KiB. Production headers and redirects are versioned.

DNS, Pages hostname redirects, repository metadata, live downloads, and the canonical production smoke remain unchecked until external activation. Follow docs/public-site-launch-checklist.md; do not infer those results from the local build.
