On a page taller than the screen, whatever sat above the first selectable
row or below the last could scroll away for good: the frame always pulled
the highlight into view, and nothing up there could take it. Now, with the
highlight on the first row, up scrolls the page a line instead, and on the
last, down does, until the page's real top or bottom is in view. Home and
End take the page to its ends with the highlight.
The highlight may leave the screen meanwhile, on purpose. The snap-back
brings it home: while it is out of view, the other arrow, Enter or Delete
only bring it back, and do nothing else, so nothing runs that cannot be
seen. Any other key ends the edge scroll.
It lives in Screen.edge_scroll, asked before a screen's own handle; select
and reorder lists, the node page, chat, message paths, the path composer,
records and the TX sweep answer cursor_at_edge. CLAUDE.md names the rule.
