+;; Movement :keys carry both the ANSI arrow escapes and Plan 9's kernel arrow
+;; runes (Kup U+F00E, Kdown U+F800, Kleft U+F011, Kright U+F012 —
+;; /sys/include/keyboard.h). Which form a terminal delivers varies, so we bind
+;; both: alacritty9 sends ANSI ESC[ for up/left/right but the raw Kdown rune for
+;; DOWN (measured on 9front — down-movement in-game needs U+F800 or it's dead);
+;; the bare text console sends all four as runes; rio's own windows swallow the
+;; arrows for scrollback. Binding both forms makes movement work wherever a key
+;; actually reaches us.
