Introduce a new UI design asset extraction flow: add POST /api/editor/ui-designs/assets/extractions handler that always uses gpt-image-2 with the fixed prompt "提取画面中的所有独立并整理成spritesheet"; parse Data URL references, call OpenAI image edits, return a spritesheet and sliced icon assets. Increase request body limit for image Data URLs and wire the route with bearer auth. Add platform-image slicing: slice_generated_icon_spritesheet_all_by_connected_components (with auto-naming "素材 1..N", foreground estimation and heuristics) and export it. Add Rust tests for the handler, prompt constant, and slicing behavior. Update frontend client and integration tests to call the new extractEditorUiDesignAssets API and verify spritesheet + icon layers are added to the canvas and persisted. Update multiple docs to describe the extraction UI, toolbar placement, and related audio/playback pitfalls. Minor related updates: toolbar button ordering and audio duration / signed read-url notes.
Adds Seedance 2.0 reference-media constraints and forbids video data URLs; updates docs/decision-log and pitfalls to record the new rules. Introduces typed audio params (type: one-shot|loop, tempo: number|null), generator-specific placeholder styles/avoidance and UI changes for generation panels. Implements related front-end changes (new crop/ raster edit components, many image-editor models, tests and workflow hooks) and server-side contract/handler updates across api-server, shared-contracts, platform-audio, platform-image and vector_engine_audio_generation to support the new submission/asset flow and validations.
Add unified placement and UI updates for canvas generation: docs require ImageCanvasGenerationPlacementModel to compute placeholder positions (avoid overlaps, center viewport on placement) and limit frontend video model entries. Refactor UI components and tests: expose div props on PlatformFloatingMenu, make PlatformInlineOptionButton forwardRef, replace inline placeholder actions with ImageCanvasGenerationImageOptionsView in basic generation composer, enhance character animation panel with parameter menu portal and option choices, add reference chip UI, and update many tests to match new interactions and labels. These changes align generation workflows, accessibility labels, and positioning behavior across editor panels.
Remove backend-assembled raw Prompt and copy action from image info; render a lightweight generationInputs snapshot (user panel inputs + reference thumbnails) stored on canvas layers and shown in the image info dialog. Unify canvas display and info to use originalWidth/originalHeight (Resolution) instead of saved Size and hydrate legacy layout width/height only as fallback. Add model/aspectRatio/imageSize options for character/icon generation (frontend state, tests, and client payloads). Increase Axum JSON body limit for character animation endpoint to 12MB for compatibility and prefer submitting persisted objectKey over large Data URLs. Update tests, docs, and related server/frontend code to reflect these behaviors and validations.
