- Add `useEffect` to check `router.query.tag` and redirect to `/blog` if: - no tag is provided - tag is an empty string or only whitespace - URL contains `?tag=` with no value - Trim `activeTag` to avoid false positives from whitespace
- Use `useEffect` to redirect to `/blog` if active tag exists but has zero posts - Prevent users from landing on empty tag pages
