"""
The photo backup section in Settings, measured in Chrome at phone widths
(harness/photo_sync_probe.py). Android's WebView is the only engine that ever
shows it.

A group, a folder or an album is named by somebody else and often has no space
in it; one such name made a 360px page 634px wide before `.settings-name`, and
a page wider than the screen takes every pinned header with it (CLAUDE.md).
