QR scanning:
- Run BarcodeDetector and jsQR in parallel — jsQR starts after JSQR_DELAY_MS
(1.5 s) so both decode simultaneously. BarcodeDetector silently returns empty
arrays for some QR variants; running jsQR in parallel via a separate rAF loop
(rafId2) and its own off-screen canvas catches those cases. First decoder to
find anything calls handleQrResult and sets qrFound = true; the other stops.
Price extraction (two bugs):
- ScanLabel: unitPrice was catalogMatch?.UnitPrice ?? 0m, ignoring aiResult
.UnitCostPerLb entirely when no catalog match — changed to fall through to AI result
- AppendOffer: only read JSON-LD "price" field; Shopify AggregateOffer uses
"lowPrice" instead — now checked as fallback so Prismatic Powders prices are found
Camera pre-warm:
- Reverted localStorage approach (caused getUserMedia to fire on every page load,
showing Chrome's "Ask" prompt immediately before user clicked anything)
- Restored Permissions API gate: preWarmCamera only calls getUserMedia when
navigator.permissions.query returns 'granted', never risks a page-load prompt

- 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

When AI Lookup fetches a manufacturer product page, it now extracts the
og:image (Open Graph) meta tag before stripping HTML tags. The image URL
is returned in InventoryAiLookupResult.ImageUrl and automatically shown
as a preview on the Create/Edit form alongside the other filled fields.
The preview includes a Remove button to clear the image, and the Wrong
Match? button clears it along with the other AI-filled fields.
On the inventory Details page a product image card is rendered above the
Stock & Pricing card whenever ImageUrl is set. The field is nullable so
existing records and powders without an image are unaffected.
New field: InventoryItem.ImageUrl (nvarchar, nullable).
Migration: AddInventoryItemImageUrl.
