Large changes across frontend, backend and docs to align creation-tab and generation-page behavior with new product UI/UX and Spacetime bindings. Updated hermes decision-log and pitfalls with concrete rules (banner carousel, font sizing, unread-dot tokens, template-card layout, direct card->entry routing, separation of account balance vs prize pools, removal of global page card shell, generation progress milestones and unified circular progress, and background video handling). Added GenerationProgressHero component and media assets, plus generation-related UI/tests updates (CustomWorldGenerationView, BarkBattleGeneratingView, creation hub/cards, platform entry routing, index tests). Backend and contract updates include new category fields in admin API types and admin UI form/list, spacetime-client/module/migration changes and generated bindings script. Misc: many tests adjusted, new docs and plan files added, and several server-rs crate changes to support the updated creation/ generation workflows.
Replace uses of the legacy `gpt-image-2-all` model with `gpt-image-2` and standardize image workflows: no-reference generation uses POST /v1/images/generations, any-reference flows use POST /v1/images/edits with multipart `image` parts. Update SKILLs, generation scripts, decision logs, and docs to reflect the contract change and edits-vs-generations guidance. Apply corresponding changes across backend (api-server match3d/puzzle modules, openai image adapter, mappers, telemetry, spacetime client/module), frontend components and services (Match3D, Puzzle, CreativeImageInputPanel, runtime shells), and add new spritesheet/parser files and tests. Also add media/logo.png. These changes align repository code and documentation with the VectorEngine image API contract and update generation/upload handling (green-screen -> alpha processing, spritesheet handling, and related tests).
