## Why

Users navigating to `/videos`, `/podcast`, and `/about` are landing on a 404, which breaks core site navigation and discovery. Fixing this restores expected browsing and improves user experience.

## What Changes

- Fix routing/serving so `/videos`, `/podcast`, and `/about` resolve to the actual generated pages instead of a 404.
- Ensure the fix applies in the deployed static hosting setup (nginx/Docker) and matches local expectations.

## Capabilities

### New Capabilities

<!-- None (bug fix only) -->

### Modified Capabilities

- `seo-content-surface`: Ensure indexable pages `/videos`, `/podcast`, and `/about` resolve correctly in deployed static serving environments (including requests without a trailing slash).

## Impact

- Static server configuration (nginx) and/or build output serving behavior.
- Improves navigation reliability and reduces drop-off from broken links.
