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.
Backend: stop treating background music as a required draft asset and remove auto-submit/plan for background music; load persisted generated UI/assets into Match3D agent session responses (added helpers to resolve profile id and fetch existing generated assets). Frontend: make Match3D result preview reuse runtime UI styles, unify runtime settings entry, update PuzzleRuntime to apply immediate pointermove transforms (disable drag transition), use SVG clipPath for merged piece rounding, ensure PuzzleRuntimeShell supplies platform theme classes, and adjust related tests. Docs & logs: update decision log, pitfalls and product docs to reflect these changes.
