# performable = Ghostty consumes the key ONLY if there's actually a Ghostty split
# to move to. At an edge — or inside herdr, where Ghostty sees a single surface —

# plugin (or nvim directly) handles the hop. One binding, works in all three.

# Clear screen. clear_screen doesn't work under herdr (the TUI repaints over it),
