Generation rules
Placeholders:
{title} {color} {material} {variant} {sku} {descriptor} {n} (image number in product)Best practice: keep alt text under ~125 characters, don't start with "image of" or "photo of" (screen readers already say "image"), lead with the product type + key attributes, keep it unique per variant, and end with a period. These are editable drafts built from what you type — always give them a quick human review.
Slugged into a safe filename using the rules below. Same placeholders as above.
