128×128, 48×48, and 16×16 PNG icons (no rounded corners baked in)

Manifest V3 fields validated (version, permissions, host_permissions)

Privacy practices disclosure matches what the extension actually collects

Single purpose clear in description and UI

Each permission justified; narrow host patterns where possible

Store listing: title, short description, detailed description, category

At least one screenshot showing core UI (correct locale if localized)

Optional promo images meet dimension guidance

Tested in a clean profile with production build (not unpacked dev quirks)
