// golem15_journal_image_variants (P33-43): the thumbnail of the original at
// Width by Height (Key, in the original's format) and its WebP copy
// (WebPKey), both blob keys of the uploads bucket. SourceWidth and
// SourceHeight are the original's size. One row per file and width, so the
// API lists a post's variants with one query instead of storage lookups.
