Studio did not expose the LoRA session options supported by several models. Add a shared, separate LoRA adapter group with path, strength, Clear, and server-side folder browsing. Controls are derived from the model specs for Qwen3-TTS, Qwen3-ASR, VoxCPM1/2, Fish Audio, CosyVoice3, F5-TTS, OuteTTS, and VibeVoice.
Adapter changes take effect through model reloads before generation. Clearing restores base weights; a blank strength preserves model-specific defaults. Loaded adapter settings survive reopening Studio, while server-configured settings are read-only. F5-TTS uses its existing configured-model route; this PR does not add a native catalog package for it.
ACE-Step and YuE2 use the same visual group and dividers. YuE2 retains its independent AR/NAR paths, strengths, uploads, and Clear buttons. Directory browsing reuses the Models-folder dialog without changing the Models folder when selecting an adapter. Individual checkpoint paths remain supported.
Includes documentation and the regenerated embedded UI. No C++, inference, GGML, or model-spec changes.
Validation:
Backend logs confirmed adapter merges. Both audio models produced different audio with their adapters enabled. Browser runs completed without page errors. These tests validate UI/session wiring, not adapter quality or a performance improvement.
