# ─── Claude Code TUI Compatibility ────────────────────────────────────

# OSC 52 clipboard, OSC notifications, and image protocols.
# Critical for Claude Code's rapid TUI updates inside tmux.

# key combos that plain terminals would swallow (Ctrl+Shift+key, etc.)

# Signal true color support to apps inside tmux.
# Without this, Claude Code falls back to 256-color ANSI palette (washed-out).

# Ensure TERM is correct in the global environment.
# Prevents inherited TERM=dumb (from launchers/IDEs) from disabling colors.
