kitty is the primary terminal. It runs in three modes: plain kitty (kitty owns splits and tabs), a tmux host, and a herdr host. Ghostty is a tmux-only terminal: every window attaches to tmux, and its ctrl+shift chords drive tmux.

Page	Source	What it covers
kitty	external repo via `.chezmoiexternals/kitty.toml`	Main config, host configs (tmux, herdr, goliath), kittens, custom tab bar
Ghostty	external repo via `.chezmoiexternals/ghostty.toml`	tmux-only terminal: ctrl+shift chords → tmux, themes
tmux	external repo via `.chezmoiexternals/tmux.toml`	Prefix, bindings, kitty-style tabs with Nerd Font icons, resurrect/continuum persistence
herdr	external repo via `.chezmoiexternals/herdr.toml`, plus `dot_config/herdr-nvim/`	Agent-aware multiplexer: keys, theme, plugins, Claude hook

Shared conventions

Font: VictorMono Nerd Font everywhere.
Background opacity 0.9, no window decorations; the compositor provides blur.
Prefix ctrl+b in tmux and herdr. kitty and Ghostty translate chords into the prefix byte \x02 plus a key, so the same physical shortcut works across hosts.
ctrl+h/j/k/l moves between panes across nvim, kitty, tmux, and herdr (vim-aware handoff at every layer).
