## Runtime
- Node.js + Express

- Let's Encrypt certificate for `free1.sj88ai.com`
- Public ads runtime can be toggled by `PUBLIC_ADS_ENABLED` (`0` = off, `1` = on)

## TTS Runtime Default
- Provider: Gemini API
- Default model: `gemini-3.1-flash-tts-preview`
- Fallback chain: `gemini-3.1-flash-tts-preview` -> `gemini-2.5-flash-preview-tts` -> `gemini-2.5-pro-preview-tts`
- `generate-scripts` supports 3.1 `Auto Emotion` mode (toggle + level 1..5) with `Emotion Diversity` strict mode by default
- 3.1 auto-emotion now applies anti-repeat memory (`20` recent accepted patterns per user+project+mode) and retries on emotion pattern repeats
- Details: `docs/runtime_tts_3_1.md`

## Global Key Policy (Free Runtime)
- Key routing: `user key > global key` only
- Runtime no longer uses env key fallback (`GEMINI_API_KEY`, `GEMINI_API_KEYS`) for Gemini key candidate rotation
- Admin can replace all global keys in one request: `POST /api/admin/keys` with `action=replace_global`
- Startup seed (DB empty only): configure `GLOBAL_GEMINI_KEYS_SEED` (+ optional `GLOBAL_GEMINI_KEYS_SEED_ENABLED=1`)
