/**
 * A UI component providing a small floating input box used inside CAD editing
 * workflows. It supports both single-input (distance, angle, etc.) and
 * double-input (coordinate entry) modes.
 *
 * The component is responsible for:
 *
 * - Creating, styling, and destroying its HTML structure
 * - Handling keyboard events (Enter, Escape)
 * - Managing live validation (via built-in or custom callback)
 * - Emitting commit/change/cancel events
 * - Ensuring no memory leaks via `dispose()`
 *
 * This abstraction allows higher-level objects such as AcEdInputManager to
 * remain clean and free from DOM-handling logic.
