1/**
2 * @file FieldPanel.js
3 * @description A layout-only web component that provides the gray panel chrome used in the bulk
4 * editor sidebar (background, padding, optional header). All content is slotted and stays in the
5 * light DOM — fully queryable from outside. No business logic or internal state.
6 *
7 * @class FieldPanel
8 * @extends WebComponent
9 *
10 * @example
11 * <!-- Basic panel with header -->
12 * <field-panel-element title="Pricing" subtitle="Set price and fees">
13 *     <form-field-element type="number" label="Price" prefix="$"></form-field-element>
14 * </field-panel-element>
15 *
16 * @example
17 * <!-- Bulk editor panel (activated by sidebar JS via data-field) -->
18 * <field-panel-element data-field="status" data-size="half" title="Status">
19 *     <form-field-element type="dropdown" label="Ticket status"></form-field-element>
20 * </field-panel-element>
21 *
22 * @attribute {string} title     - Bold header title (plain text, HTML-escaped)
23 * @attribute {string} subtitle  - Gray subtext rendered below the title
24 * @attribute data-field         - Identifies the bulk editor field; read by sidebar JS to show/hide the panel
25 * @attribute data-size          - 'half' | 'full' — controls grid column span in the values grid
