ui::Choice

A list of things to do, as a sheet (ui/action_sheet.cpp): each line's label, and what it runs once the sheet has closed; its icon (a Cadran icon, nullptr: none), what is set now at its end (detail), its group (a section starts where it changes, its name the kicker above it) and its tone (ON: the detail in teal, WARN: amber, DANGER: a removal, in coral); switched(): a switch at its end, on or off, instead of the detail. A line without run only closes the sheet. subtitle, under the title: what it is about now; image, an NVG image before the title (someone else's, kept). The first line is selected; none, no sheet.
