Overview

Full-screen alternate-buffer question form built directly on Bubbletea.

Opens a new terminal screen (like fzf/vim) via alt_screen: true, renders select/multi-select forms with Lipgloss styling, handles keyboard input through Bubbletea’s raw-mode event loop (termios), and restores the original screen when done.
