 ## 2026-10-07 — tmux dim inactive panes
 Done: window-style / window-active-style added. Two traps: colour234 ≈ iTerm2 dark bg (#15191f) → invisible; `window-active-style bg=default` inherits window-style since tmux 3 → active pane dimmed too, terminal colours hardcoded instead (fg #dcdcdc, bg #15191f). Inactive settled at #353d48 / #a6acb6 after 3 live rounds. Light macOS theme would need the inverse. Merged feature/tmux-dim-inactive-panes → develop.

+Done: choose_macos_shell default bash → zsh (Enter, no tty, unknown value). Found: `curl | bash` path never asked USER/EMAIL (stdin = pipe → `[ -t 0 ]` false → login name + empty email, bash, no offers); remote-install.sh now runs install.sh `</dev/tty` when openable. Found: BRANCH default `master`, origin has only `main` (raw URL 404) → `main`. Lint OK, chooser tested 4 values. Branch feature/macos-zsh-default, not merged. Other session: feature/repo-sync open (CLAUDE.md layout already lists repo-sync).
