 ## Component architecture
 
-- **zsh** (`zsh/.zshrc`): Powerlevel10k instant prompt + [antidote](https://github.com/mattmc3/antidote) plugin manager (plugin list in `zsh/.zsh_plugins.txt`). `.zshrc` sources optional layered configs if present: `.powerline_config`, `.user_config`, `.virtual_env_config.zsh`, `.mac_config.zsh`, `.local_config`. `update_dotfiles()` auto-`git pull`s this repo in the background on every shell start. Machine-local overrides belong in `.local_config` (not committed).

Machine-local overrides belong in `.local_config` (not committed). [atuin](https://github.com/atuinsh/atuin) records history with cwd/exit code and owns Ctrl-R (over fzf); its config is `.config/atuin/config.toml` via `ATUIN_CONFIG_DIR`, data stays in `~/.atuin`.
 - **nvim** (`nvim/init.vim`): [vim-plug](https://github.com/junegunn/vim-plug), auto-bootstrapped on first launch (`:PlugInstall`). Python provider points at the `~/python-envs/neovim` virtualenv on Apple Silicon. `colors/` holds a large bundled colorscheme collection.
 - **tmux** (`tmux/.tmux.conf`): TPM-style `plugins/`. `tmux/tmux_attach.sh` is an attach helper. On macOS, `.mac_config` binds `prefix+P` to `tmux/op_password_paste.zsh` (pastes a 1Password password into the pane, e.g. remote sudo; needs the `op` CLI with app integration).
 - **alacritty** (`.config/alacritty/`): active theme selected via the `import = [...]` line in `alacritty.toml`.
