Warn on small picture candidates

agent.md

@@ -186,6 +186,7 @@ There are three selectable data sources:
 - Source discovery: use manufacturer mapping from Local scrape DB and show exactly which source produced each candidate.
 - Browser scraping: use the configured browser engine per source and keep the UI responsive while scraping runs.
 - Image extraction: collect original image URLs, dimensions, mime type, file size and source page URL.
+- Image quality: show a clear warning for any picture candidate smaller than `800 x 800`; small thumbnails must remain visible for review but must be marked as not production-ready.
 - Duplicate detection: calculate `sha256` for exact duplicates and perceptual hash for visually similar images.
 - Target assignment: propose whether pictures belong to `color`, `size`, `combination` or `manual` target, then learn from user corrections.
 - Persistence: save picture blobs, candidates, hashes, source metadata and learned rules only into Local scrape DB.
