# v1.10.8c: per-pane tmux sessions (boolab pattern). With one session per
# pane, the session size adapts to the attached client; `window-size = largest`
# + `aggressive-resize on` make tmux pick up the client's actual cols/rows
# instead of falling back to 80x24. Critical for opencode/claude TUIs that
# read TIOCGWINSZ once at fork time.

# v1.10.3: `set -g mouse on` removed. tmux's mouse mode captured wheel/touch
# events at the protocol level, so xterm.js never saw them and the viewport
# couldn't scroll on mobile. With mouse off, xterm.js handles scrollback
# natively (wheel on desktop, finger-drag on mobile via touch-action: pan-y).
# Tradeoff: lose tmux mouse pane-resize and scroll-inside-vim; acceptable for
# the homelab single-user setup.

# v1.10.1: shells drop privs to samkintop (uid 1000) so the terminal runs in
# the user's environment, not root. `env HOME=… USER=…` is required because
# gosu only changes uid/gid — env (including HOME) survives, and the tmux
# server runs as root so HOME would otherwise be /root. bash -l then sources
# samkintop's ~/.profile / ~/.bashrc to pick up PATH (nvm, ~/.local/bin,
# ~/.opencode/bin).
# v1.10.2: su-exec → gosu (alpine → debian; functionally identical).
