User Story

As a Kitty+tmux user, I want optimized terminal passthrough settings so that Claude Code keybindings, true color, and undercurl rendering work correctly inside tmux.

Context

Running Kitty 0.47.1 on Arch with tmux-git (next-3.7). Default tmux config drops extended key sequences and lacks true color passthrough, breaking Claude Code keybindings and diff rendering.

File Targets

  • .tmux.conf — add Kitty optimization block

Acceptance Criteria

  • True color renders in tmux (printf "\x1b[38;2;255;100;0mTRUECOLOR\x1b[0m\n")
  • Extended keys forwarded (Claude Code keybindings work)
  • Undercurl renders in nvim
  • Clipboard passthrough via OSC 52

Test Expectations

  • Manual verification of color, keys, clipboard, undercurl

Constraints

  • Must not break Mac/Linux cross-platform compatibility

Checklist

  • Changes applied
  • tmux reloaded and tested
