# yazi — the flagship file manager: a fast, keyboard-driven TUI that
# fits the distro's identity (Ghostty's Kitty-graphics previews, rofi
# menus, everything from one JSON). Themed from theme-state.json and
# shipped with a curated plugin set. The GUI half (Thunar, "open folder"
# handler) is nomarchy.system.fileManager on the system side.
#
# `y` (the shell wrapper) cd's the shell to yazi's last directory on
# exit; SUPER+E opens it in a fresh terminal.
