Uses Permissions API (non-prompting) to check camera state on load.
If state === 'granted', silently starts the stream so Scan Label opens
instantly with no browser prompt on subsequent page visits. Falls back
gracefully when Permissions API is unavailable or permission is 'prompt'.

- Use BarcodeDetector API (Chrome/Edge/Android) as primary QR scanner; it uses
native OS-level decoding which is far more reliable than jsQR for Prismatic's
QR codes. Falls back to jsQR (attemptBoth) on Safari/Firefox.
- Keep MediaStream alive between modal opens so the browser does not re-prompt
for camera permission on each scan within the same page session. Stream is
released after 2 min of idle (IDLE_RELEASE_MS) or on page unload.
- stopCamera() split into stopQrLoop() (cancel rAF only) and releaseCamera()
(stop tracks + null srcObject); modal hide now calls stopQrLoop, not releaseCamera.

- LookupByUrlAsync now maps all identity + spec fields from Claude response
(manufacturer, SKU, colorName, description, sdsUrl, tdsUrl, unitCostPerLb, etc.)
Previously only augmenting fields were mapped; Columbia QR path left 80% blank
- Vision scan follow-up: after ScanLabelAsync reads label text, automatically run
LookupAsync using the extracted manufacturer + color/SKU to fill SDS/TDS URLs,
product page, image, description, and any specs not printed on the bag;
label values (cure schedule, SKU) remain authoritative and are never overwritten
- SDS/TDS URL extraction: added ExtractDocumentLinks() that scans anchor tags in
raw HTML before tag-stripping, injects found URLs as [Structured Data] lines so
Claude can read and echo them back in the JSON response; previously all hrefs
were lost with the HTML stripping
- Added SdsUrl/TdsUrl to InventoryAiLookupResult, Claude system prompt JSON schema,
LookupAsync mapping, and ScanLabel response (catalog match ?? aiResult fallback)
- SDS/TDS now also stored on auto-contributed catalog entries
- jsQR inversionAttempts: 'dontInvert' → 'attemptBoth' for better QR detection
under varying label contrast and lighting conditions

- Platform PowderCatalogItem table (IPlainRepository, no tenant filter) with
full spec fields: cure temp/time, finish, color families, clear coat flag,
coverage sq ft/lb, transfer efficiency, IsUserContributed
- Two EF migrations: AddPowderCatalogItem + AddPowderCatalogSpecFields
- PowderCatalogController (SuperAdminOnly): import from Prismatic JSON scrape,
Lookup AJAX endpoint (catalog-first, ranked by SKU exact match), stats view
with Tenant Contributed card
- Unified smart Lookup button on inventory Create/Edit: catalog hit fills all
fields via catalogSnapshot pattern; AI augments cure/finish data from product
URL if subscription enabled; catalog miss falls through to AI lookup
- In-browser label scanner (_LabelScanModal): getUserMedia live camera feed,
jsQR auto-detects QR codes in rAF loop; "Scan Label Text" fallback sends
captured frame to Claude vision via /Inventory/ScanLabel
- ScanLabel endpoint handles both QR URL path (LookupByUrlAsync) and vision
path (ScanLabelAsync); auto-inserts unrecognized products as
IsUserContributed=true; returns wasInCatalog/addedToCatalog flags
