The embedded backup center's fragment kept its standalone-page skeleton
(.container + .sidebar restyled by a pile of overview.css overrides).
.container's fixed viewport height inflated the Backups tab pane to
~100vh, stretching the pane surface far past the content and under the
footer buttons, and the restyled strip never matched the app-detail
Config sub-tabs.
Rebuild backup-content.html on the canonical sub-tab idiom instead —
.tabs-wrapper > .tabs-list (emoji tab-buttons) + .tabs-content card,
with a .backup-actions footer below the card mirroring .config-actions.
The bespoke overview.css restyle block, the nebula special-cases, the
embed's id-stripping and BackupPage's dead page-header updater all fall
away; the export menu now opens upward from the footer.
