- Bumped caller token budget (200-550 range, was 150-450)
- Added 20 layered/morally ambiguous caller stories
- Valentine's Day awareness in seasonal context
- Default LLM model: claude-sonnet-4-5 (was claude-3-haiku)
- Publish: SCP-based SQL transfer (fixes base64 encoding on NAS)
- Favicons: added .ico, 48px, 192px PNGs for Google search results
- Website: button layout cleanup, privacy page, ep12 transcript
- Control panel: channel defaults match audio_settings.json
