TUI Design System Design around the user's repeated action, the data they must keep in view, and the terminal capabilities actually available. Keep input responsive under slow I/O and make selection, focus, and operation state explicit. Primary documentation checked: 2026-09-04. Framework APIs change; use the project's versions. Follow the project's visual identity (SilkCircuit Neon for the maintainer's personal tools) rather than treating an example palette as a universal theme.
