# dx Terminal: the tmux server behind the browser's Terminal tab, shared by

# Everything not set here is a tmux default, including the C-b prefix.

# Panes see a tmux terminal with true color; the outer terminal is dxd's PTY
# (TERM=xterm-256color) rendered by ghostty-web, which supports RGB, the
# xterm modifyOtherKeys extended keys, OSC 52, and focus reporting.
