/**
 * FlowBoardColumnItemComposer - A composer for creating new items in a FlowBoard column.
 *
 * @description
 * Provides a trigger+form pattern for adding new items to a column.
 * This component is completely data-agnostic - it accepts any data structure.
 * The user provides their own form fields via the `form` slot.
 *
 * @remarks
 * The composer emits generic `create` events with user-defined data:
 * - Element properties (title, description, labels, etc.)
 * - Metadata (userId, tags, priority, appointments, custom fields, etc.)
 * - Any other data the application needs
 *
 * @name FlowBoardColumnItemComposerElement
 * @element mosaik-flow-board-column-item-composer
 * @category Layouts
 *
 * @slot trigger - The trigger element that opens the form (e.g., "Add another item" button)
 * @slot form - The form content for creating new items (completely user-defined)
 *
 * @csspart container - The main container element
 * @csspart trigger - The trigger section wrapper
 * @csspart form - The form section wrapper
 *
 * @cssprop {String} --flow-board-composer-padding - Padding for the composer
 * @cssprop {String} --flow-board-composer-gap - Gap between form elements
 *
 * @fires flowBoardBeforeItemCreate {FlowBoardBeforeItemCreateEvent} - Fired before item creation (cancelable)
 * @fires flowBoardItemCreate {FlowBoardItemCreateEvent} - Fired when item is created with user-defined data
 *
 * @example
 * Basic usage with simple form:
 * ```html
 * <mosaik-flow-board-column-item-composer id="composer" slot="footer">
 *   <mosaik-button slot="trigger" label="Add item"></mosaik-button>
 *   <div slot="form">
 *     <mosaik-textbox id="title" placeholder="Enter title…"></mosaik-textbox>
 *     <mosaik-button id="add" label="Add"></mosaik-button>
 *   </div>
 * </mosaik-flow-board-column-item-composer>
 *
 * <script>
 *   document.getElementById('add').addEventListener('click', () => {
 *     const composer = document.getElementById('composer');
 *     const title = document.getElementById('title').value;
 *     composer.create({ title });
 *   });
 * </script>
 * ```
 *
 * @public
