# install-omadots-extras.sh — developer polish from omadots.
# Cherry-picked configs from https://github.com/omacom-io/omadots (the Omarchy
# team's shared dotfiles), adapted to layer cleanly on NoSignal:
#
#   starship.toml      -> ~/.config/starship.toml   (replaces Caelestia symlink)
#   tmux.conf          -> ~/.config/tmux/tmux.conf
#   btop.conf          -> ~/.config/btop/btop.conf  (replaces Caelestia symlink)
#   omadots.gitconfig  -> ~/.config/git/ + git include.path (identity untouched)
#   LazyVim starter    -> ~/.config/nvim            (ONLY if absent — never rm -rf)
#
# Unlike omadots' own install.sh, nothing here overwrites ~/.bashrc or deletes
# an existing nvim config. Safe to re-run (idempotent).
