Initial Ghostty config for macOS, using native tabs/splits in place of tmux passthrough for in-terminal session management. Window: - Translucent background (background-opacity = 0.7) with macOS blur (background-blur-radius = 20). NOT fullscreen — macOS native fullscreen silently disables window-level transparency. Resize manually (green button or Rectangle/Spectacle); window-save-state retains the layout across launches. - macos-titlebar-style = tabs, copy-on-select to clipboard, mouse-hide-while-typing, 6px internal padding. Behavior: - macos-option-as-alt = left so emacs-style \e<key> bindings reach the shell. On macOS, left-option composes Unicode by default (option+c → ç), which silently broke fzf-cd-widget (Alt+C) and any other Alt-prefixed zsh binding. Right option still composes accents (option+e e → é). Keybindings: - Cmd+Arrow navigates splits, Cmd+Shift+Arrow resizes, Cmd+Z toggles split zoom, Cmd+, renames the current tab, Ctrl+Tab / Ctrl+Shift+Tab cycles tabs.

Catch invalid keybind actions, unknown config keys, and other ghostty-rejectable mistakes at commit time instead of at next reload. Skips silently if ghostty is not on PATH (Linux dev boxes). Caveat: validates the .tmpl as-is. The current ghostty config has no Go-template syntax, so chezmoi passes it through unchanged. If templating is added later, the hook will need to render via `chezmoi execute-template` before validating. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
Experimenting with Ghostty: native tabs and splits, embedded fonts, translucent blurred background, and emacs-style Alt key handling on macOS.
