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.
- Renamed src/MediaSidebar.html to src/MediaManager.html to align with modal UI.
- Fixed race condition in Photo Picker polling preventing duplicate imports.
- Updated global.ts, initMenu.ts, and mediaHandlers.ts used in the fix.
- Fixed unit tests for mediaHandlers.
- 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
- Implemented modular status automation system (statusHandlers.ts).
- Added handlers for 'Published' (Active/Qty 1), 'Sold' (Active/Qty 0), and 'Drafted'.
- Refactored onEdit triggers into a central Router pattern in OnEditHandler.ts.
- Updated Product.ts to support explicit quantity setting (fixed 0 value bug).
- Updated shopifyApi.ts to implement SetInventoryItemQuantity (using ignoreCompareQuantity).
- Consolidated triggers into single onEditHandler.
- Updated project documentation.
- Implemented a global toggle to enable/disable background queue processing.
- Added a Side Panel (Sidebar.html) to view pending edits.
- Added per-item controls: 'Delete' to remove from queue, 'Push' to force update.

- Updated documentation (README, ARCHITECTURE) to reflect new features.
- Fixed 'clasp' deployment issues by cleaning up manifest management.
