🎯 Use case

This file lives under “components/”, which covers shared React UI pieces. On the API surface it exposes isVimModeEnabled, getNewlineInstructions, and isNonSpacePrintable — mainly functions, hooks, or classes. It composes internal code from commands and ink (relative imports).

Generated from folder role, exports, dependency roots, and inline comments — not hand-reviewed for every path.
