# The base image leaves LANG unset, which makes LC_CTYPE fall back to POSIX. tmux
# reads the locale to decide whether its client is UTF-8 capable, and in a non-UTF-8
# locale it renders every non-ASCII character of Claude's TUI as "_". TERM matters
# for the same reason on the other end: ttyd's client is xterm.js, so claim its
# capabilities rather than the "screen" default tmux would otherwise assume.
