Module sidebar 

A sidebar: a sectioned, keyboard-navigable menu column.

Sections carry an optional title (a dim, non-selectable header) and a list of selectable items. The sidebar owns the cursor, the vertical/horizontal scroll offsets and an optional / fuzzy filter; the caller reads back the selected item’s id to drive its own view. Labels wider than the column are either clipped with … (Overflow::Truncate) or kept and panned horizontally with a scrollbar (Overflow::Scroll).
