// Fix image ALT text leaking "Versa" — the CORRECT way: productUpdateMedia on
// MediaImage ids (fileUpdate rejects ProductImage ids). Iterates the versa product
// IDs, fetches current media alt, rewrites 'Versa Designed Surfaces' -> 'Hollywood
// Wallcoverings'. DRY by default; --apply writes. Resumable via done-versa-alt.jsonl.
