# RULE: moving focus is a BUILTIN like any other, so there is ONE
# implementation and every route reaches it. SPC w h/j/k/l run Left/Down/Up/
# Right — the geometric focusDir the Ctrl-w prefix also runs — and SPC w t
# plus body-normal Esc run Toggleterm, the hop between the most recently
# focused DOCUMENT (a file, an image, a +Search/+Help output buffer: things
# you READ) and the most
# recently focused TERMINAL. "Most recent" is the focus history the core
# already keeps to hand focus back when a pane closes, so the hop back is the
# same key. Focus shows up in the golden's `cursor=` header: that is the
# ACTIVE pane's cursor, so each snap is named by the pane it should land in.
