 * @slot show-password-icon - An icon to use in lieu of the default show password icon.
 * @slot hide-password-icon - An icon to use in lieu of the default hide password icon.
 * @slot help-text - Text that describes how to use the input. Alternatively, you can use the `help-text` attribute.
 * @slot increment-number-stepper - An icon to use in lieu of the default increment number stepper icon.
 * @slot decrement-number-stepper - An icon to use in lieu of the default decrement number stepper icon.
 *
 * @event syn-blur - Emitted when the control loses focus.
 * @event syn-change - Emitted when an alteration to the control's value is committed by the user.
 * @event syn-clear - Emitted when the clear button is activated.
 * @event syn-focus - Emitted when the control gains focus.
 * @event syn-input - Emitted when the control receives input.
 * @event syn-invalid - Emitted when the form control has been checked for validity and its constraints aren't satisfied.
 * @event syn-clamp - Emitted if the numeric strategy allows autoClamp and the value is clamped to the min or max attribute.
 *
 * @csspart form-control - The form control that wraps the label, input, and help text.
 * @csspart form-control-label - The label's wrapper.
 * @csspart form-control-input - The input's wrapper.
 * @csspart form-control-help-text - The help text's wrapper.
 * @csspart base - The component's base wrapper.
 * @csspart input - The internal `<input>` control.
 * @csspart prefix - The container that wraps the prefix.
 * @csspart clear-button - The clear button.
 * @csspart password-toggle-button - The password toggle button.
 * @csspart suffix - The container that wraps the suffix.
 * @csspart stepper - The container that wraps the number stepper.
 * @csspart decrement-number-stepper - The decrement number stepper button.
 * @csspart increment-number-stepper - The increment number stepper button.
 * @csspart divider - The divider between the increment and decrement number stepper buttons.
 *
 * @cssproperty --syn-input-autofill-shadow - The shadow to apply when the input is autofilled.
 * @cssproperty --syn-input-autofill-readonly-shadow - The shadow to apply when the input is readonly and autofilled.
 * @cssproperty --syn-input-autofill-text-fill-color - The text fill color to apply when the input is autofilled.
 * @cssproperty --syn-input-autofill-caret-color - The caret color to apply when the input is autofilled.
