Remove duplicate h1, fix avatar gender caching, blacklist Celeste voice

- Hide h1 (sr-only) on homepage — banner already shows show name
- Promote tagline as visual lead after banner
- Fix avatar gender: add .gender marker files, re-fetch on mismatch
- Clear stale avatar cache so all re-fetch with correct gender
- Blacklist Celeste voice from caller pool
