LoRA training (codai/api/loras.py):
- Fix instant crash "mat1 and mat2 have the same dtype (Half != float)":
  components loaded in their checkpoint's native dtype (fp16 text encoders +
  fp32 UNet). Force consistent fp32 (stable LoRA reference) for both SD1.5 and
  SDXL, and free VAE/text encoders after pre-encoding to keep memory in budget.

Web UI (tools/gen_township_fighters.py):
- Per-profile LoRA training launched from the Characters/Environments cards
  (steps/rank, live server progress, status badge); the "Train LoRAs" step now
  trains regardless of the consistency setting and logs what it does. Profiles
  are uploaded to CoderAI first so server-side training has reference images.
- New Matches page: final short/long videos, single clips, and outcome outputs
  per match. Re-render clips/outputs with the video model (reuses the render
  path, honoring keyframe/LoRA settings) or reassemble finals from existing
  clips (no model).
- Replace browser alert/confirm/prompt with proper in-page modal dialogs
  (uiConfirm/uiAlert/uiPrompt) on every page.
- Apply changed connection/model settings (image/video/text model) to the live
  session on Save config / Start, so per-profile jobs use them immediately.

Web UI (tools/gen_township_fighters.py):
- Characters and Environments management pages: edit every meta field
  (data-driven form, not a fixed set), remove a profile, delete individual
  reference images — synced to CoderAI (DELETE/PATCH).
- Regenerate references: background job generates N new images guided by the
  kept references (IP-Adapter) and APPENDS them, preserving non-deleted ones.
- Upload your own reference image files (magic-byte validated, appended).
- Clear run banner + status-pill label indicating which run/step is executing.
- Config: -s/--save and -c/--config; web Save button writes server-side and,
  when launched with -c, defaults to that same config path.

Environment parity / consistency:
- Per-environment identity LoRAs (loras.py: environment field, env image
  resolver, "place" instance prompt; script stage_env_loras, env_loras.json,
  applied to keyframes + video alongside fighter LoRAs).
- Environment IP-Adapter: environment_profiles on the image request
  (imagerequest.py) resolved into the IP-Adapter reference set (images.py),
  so environment regeneration can match kept references.

CLI: -s/--save FILE writes selected generation options to a JSON config
and exits; -c/--config FILE loads them as defaults (command-line args
still override, via a two-phase parse).

Web UI: "Save config" button writes the current form options to a file
on the server (relative paths land in the output dir, absolute paths as-is)
via a new /save-config endpoint. Web- and CLI-saved configs are
interchangeable (shared CONFIG_FIELDS / canonical mapping).

- Character profiles: extract from images/video or generate from text prompt;
  up to 6 profiles per image/video generation via IP-Adapter conditioning
- Environment profiles: same multi-slot system for scene/background conditioning
- Multi-character dialog for video: per-character TTS synthesis with voice profile
  support, sequential or manual timing, ffmpeg amix, Wav2Lip/SadTalker lip sync
- 2D↔3D conversion: image/video to stereo/anaglyph/depth/mesh and back;
  text/image to 3D model (GLB); turntable video rendering
- Generation archive: auto-save all outputs with configurable retention and
  hourly cleanup; browse/delete from web UI and API
- Voice profile enhancements: extract from video, PATCH update, GET by name;
  TTS endpoint now accepts voice_profile for F5-TTS cloning
- Image generation progress tracking via GET /v1/images/progress
- Web Studio: Profiles tab (Characters, Environments, Voices) with full managers;
  multi-slot character/environment selectors in all panels; character dialog
  section in all video panels; archive settings in Settings page
- Fix: Profiles tab sub-tab switching now correctly updates the content panel
