The ^P view grows from a static scroll window into its own dialog. Up
top, every distinct path the message took drawn in the atlas's edge
style — origin left, us right, the final relay → us link coloured by
that path's reception SNR, earlier links slate — with markers for every
node but labels only along the currently selected path, so a many-path
graph stays readable; the selected path draws bright, the rest dim.
Beneath, one row per arrival with a selection cursor: ↑↓ move it (the
graph follows), and a row longer than the dialog scrolls horizontally
with ←→ — the whole line shifts under an edge …, and snaps back the
moment the selection moves on. crop_cells in tui.render is the new
cell-exact window primitive behind that.
