Slab Spotter

Spot a slab

Grader Grade (optional, as printed)

Certification number Card text (optional — card name / set, helps find house records)

📷 Take / choose a photo of the label

The photo is decoded right here first — a QR code or barcode in it fills the cert above. If no code reads, you type the cert with the photo in view (no scrolling away). For the printed label text, run the house OCR lane (tools/spot-read.py) and import the read below — OCR runs in the house lane, not in the Spotter.
