       TWO layers, a PATTERN not a plane name: plane-backdrop.webp is the
       plane's own identity image — untracked (gitignored), living only in a
       plane's tree like .env.local, so review-loads never carry or wipe it.
       Where a plane ships none, its 404 costs nothing visible: the tracked
       alpine default underneath still renders (a failed layer in a multiple
       background does not blank the others). The plane vhost serves this one
       file must-revalidate (see plane-*.conf) because every plane answers
       the SAME URL — a 7d-cached copy from one plane would impersonate the
       next plane's identity for a week. */
