A Row with a secondary explanation line beneath it — the iOS-settings
pattern where a control carries an inline hint (e.g. what the selected option
means). The label + trailing control share the top line; detail renders
below as a muted body-small caption, optionally led by a small detailIcon
glyph so the state reads at a glance. Omit detail and it behaves like Row.
Presentational only — callers own the copy (i18n) and pass the icon.
