## Summary
- rebuild the public Tenantial homepage around an evidence-first Microsoft tenant governance narrative
- replace the old hero visual with a new static dashboard preview and add dedicated Trust Bar and Feature Pillars sections
- update the shared public shell, navigation, footer, dark design tokens, assets, and homepage content to match the new brand direction
- align website smoke coverage and Spec 400 artifacts with the rebuilt homepage
## Testing
- not run in this pass
- updated website smoke specs under apps/website/tests/smoke
## Note
- `website-dev` was pushed to `origin` so the requested PR base exists remotely
- the remote `website-dev` branch is an ancestor of `origin/dev`, so this PR may also show upstream `dev` history relative to that base
