# Loaded for every interactive shell before any ~/.zshrc, so EVERY user gets a
# working shell with no dotfiles. Personal configs (chezmoi/host) layer on top.

# Claude Code: classic scrolling renderer. The default flicker-free renderer
# repaints with absolute cursor addressing and never scrolls finalized
# transcript lines off the top, so tmux history and the browser terminal's
# scrollback stay empty — scrolling up (mobile especially) shows torn repaint
# fragments instead of the conversation. The classic renderer commits the
# transcript to scrollback as it goes.
