// create-transmittal.js — folder-creation plumbing for outgoing
// transmittals.
//
// Surfaced by events.js as a pane-menu item (right-click empty space)
// when state.scopeCanonicalFolder == 'staging'. The modal prompts for
// a ZDDC-conforming folder name (date_tracking (purpose) - subject)
// with live validation via zddc.parseFolder, then POSTs X-ZDDC-Op:
// mkdir. On success the client navigates to the new folder URL — the
// staging/ cascade serves the transmittal tool there, where the user
// builds the manifest, adds files, and publishes.
//
// No manifest assembly happens here. This is plumbing.
