This change modifies the validation/planning phase to skip the expensive thumbnail generation step in 'getUnifiedMediaState'. Since the planning phase primarily needs file IDs and names to calculate deletions, adoptions, and reorders, skipping the thumbnail verification/retrieval (including sidecar checks) significantly reduces the latency of the 'Save Changes' operation.
Updates logic to detect processing state (including READY-but-no-sources race condition) and propagates contentUrl updates to the frontend immediately.
- Resolved persistent 'SyntaxError: Unexpected token class' by refactoring 'MediaState' and 'UI' classes in MediaManager.html to standard ES5 function constructors.
- Resolved 'SyntaxError: Unexpected identifier src' by rewriting 'createCard' to use 'document.createElement' instead of template strings for dynamic media elements.
- Consolidated script tags in MediaManager.html to prevent Apps Script parser merge issues.
- Updated docs/ARCHITECTURE.md and MEMORY.md to formally document client-side constraints (No ES6 classes, strict DOM manipulation for media).
- Note: Google Drive video animate-on-hover functionality is implemented but currently pending verification/fix.
This major refactor addresses improper image matching and duplication:
- Implemented strict ID-based matching in 'MediaService', removing the greedy filename matching fallback.
- Redesigned synchronization pipeline to treat Google Drive as the Source of Truth, supporting orphan adoption (Shopify -> Drive) and secure uploads.
- Implemented 'gallery_order' using Drive file properties (supporting both v2 and v3 APIs) for stable, drag-and-drop global ordering.
- Added conditional file renaming using timestamps to enforce '_' naming convention without unnecessary renames.
- Fixed runtime errors in 'MediaService' loops and updated 'ShopifyMediaService' GraphQL mutations to match correctly schema.
- Rewrote 'MediaService.test.ts' with robust test cases for strict matching, adoption, sorting, and reordering.
- Implement DriveService and ShopifyMediaService for backend operations
- Create MediaSidebar.html with premium UI and auto-polling
- Integrate Google Picker API for robust file selection
- Orchestrate sync logic via MediaService (Drive -> Staged Upload -> Shopify)
- Add secure config handling for API keys and tokens
- Update ppsscript.json with required OAuth scopes
- Update MEMORY.md and README.md with architecture details
