Templatize Page

Given a brand's lookbook / collection / editorial URL, build an Astria pack whose prompts let the user re-shoot that page's looks with their own workspace references.

There are two variants:

• shoe-swap — barefoot-edit each lifestyle photo (remove the footwear) and build a prompt that swaps in a shoe reference. Footwear-only.
• silhouette — silhouette-edit each photo (keep only the posed figure) and build a prompt where the user picks which items to swap with references (model, shoes, outfit, bottoms, background, accessories). Whatever they don't swap is described in the prompt text instead.

Both variants end with one new pack (titled after the page), N new pose tunes (one per surviving lifestyle image), and N new prompts inside the pack.
