PicToPC 0.7.13 — Amazon UK Seller Central offers

Adds the bottom-left floating button and extension-popup support on Amazon UK's
Add offer page: /interactive/listing/workflow/offer/offer.

Fills SKU (without warehouse location), GBP price, exact item condition and saved
offer condition note. Katal shadow controls receive native input/change events.
Select a Used grade to reveal notes and images. A generic saved Used condition
keeps an existing Used grade; otherwise choose a grade in PicToPC's options.
New offers can receive SKU and price with photos and note unchecked.

Uploads 1–6 photos into an empty offer image section. Larger groups need the
explicit first-six option. Files must be JPG, PNG, GIF or TIFF under 10 MB;
photos above that limit need a smaller export. Video is never sent.
Existing offer images are not overwritten. Review thumbnails and order yourself.

The extension does not change fulfillment, other marketplaces or catalogue
details, and never submits an offer. Blank saved fields preserve existing text.
Selection is consumed before photo handover to prevent accidental double upload.

Install: extract the ZIP, reload/load this unpacked folder in Chrome, then refresh
PicToPC and Seller Central. This preview is separate from the Chrome Web Store.
Adds a content-script match only for sellercentral.amazon.co.uk listing workflows.
No Amazon API credentials, server integration or background account requests.

Validation: isolated Chrome fixtures cover Used-field rendering, native change
events, ordered photos, limits, currency guard, stale conditions, duplicate
controls and redraw recovery. Actual offer submission was not tested or performed.
