- set -euo pipefail with audit: every tolerated failure is guarded - write --theme to bat's config file, not into the themes/ directory (was: append to a directory, failed silently) - download and configure the same theme (Catppuccin Mocha; was: Macchiato downloaded, Mocha configured) - preserve MANPAGER quoting via printf (was: collapsed to export MANPAGER=bat -plman, invalid when sourced) - detect shell via $SHELL instead of $0 (was: always matched *) and reported 'Unsupported shell: bat.sh') - fish branch appends fish syntax, no more exec of a mangled command string - check pacman/apt bat install results (was: unchecked, continued on failure) - idempotent appends (grep guard), tty-guarded fish warning - remove broken rc-sourcing block (sourced .zshrc/config.fish from bash)
