The admin signs in with the shared password, creates a Menu Set, drops photos
into it (shrunk in the browser first), reorders Pages by dragging or with
up/down buttons, previews the Draft exactly as customers would see it, and
publishes it over the previous set. Restore and delete close the loop. Mutations
need a session, a same-origin request and a CSRF token derived from the session;
a Draft's media is served only to a session holder.
Landing page, Section pages and archived sets rendered per request from the
store, with the approved design: hand-written CSS, self-hosted Archivo, a
copper pour line in the Section rail, an admin-only Thumbnail and a text page
index. Media is keyed by Page id so URLs survive publishing, and a Draft's
media needs a session. Includes the scrypt admin auth and the login throttle
the media rule needs.
