Unselected rows middle-elided to the width while the highlighted one kept its
natural line and cracked at the lane, so moving the cursor rewrote the row
under it — two renderings of the same walk, differing in more than the shift.
The `⋯` rescue exists to save a route's two endpoints from a right truncation.
On this board both endpoints are the same `★` on every row, by construction, so
it spent three cells and a hop to arrive back at the one thing the reader
already knew, while the walk's *front* — the part that actually differs from
row to row — paid for it. Every row now carries the whole line and is cut by
the list, so selected and unselected differ in exactly one thing: the shift.
The title is a finished Text rather than a width-aware callable now (nothing
fits itself to the terminal any more), which retires the per-width memo — a
frozen record composes once per open instead.
