 * the same caption line as the wall it builds. The tokens below are copied from
 * src/assets/page.css on purpose - the app and the page must not drift apart.
 *
 * The screen is one column with one job per row:
 *
 *   header    who this is, and the promise that nothing is uploaded
 *   frame     the photo box: what is happening now (drop / progress / result)
 *   caption   one line of standing help, never status
 *   details   the settings, above the action they affect
 *   actions   exactly one forward button for the current step
 *
 * Contextual buttons live inside the frame (change photos, cancel, preview) so
 * the bottom bar never offers two equal choices.
