 *  documented in `chat-message-row.tsx`'s skeleton). No fake inner
 *  placeholder cruft — a real loading iframe shows a blank rectangle.
 *
 *  Exported so a viewer that is still RESOLVING where its frame points
 *  (ClaudeEmbed probing for a self-hosted mirror, before it has a `src`)
 *  can render the IDENTICAL skeleton through `EmbedViewerFrame`, keeping
 *  every embed's loading state 1:1 with the Figma/Sheets/PDF viewers. */
