Detailed Description

A single-line text input component.

Renders a fixed-width bordered box containing a label on the left and the current value on the right. When focused, the box is highlighted with a distinct colour. The component accepts printable character input, handles Defs::Special::Backspace for deletion, and fires on_change on every modification.

Rendering example (focused, value = "CPGen")
