Pixel Panes
Ten ways a Claude Code mod pane could look. Each window is drawn on a real 128×36 terminal grid at true cell proportions, with the limits a mod has. One pixel is half a character cell (the ▀ ▄ trick) unless the card says otherwise, and text never sits on top of pixels.
“Paint like my tmux” copies what we saw in tmux: background colours came out gray, so a cell that needs two colours loses its bottom half, and Image panes show their alt text.
