/**
 * WPBC BFB Pack: Divider (Horizontal / Vertical line) — Schema-driven, Factory Inspector
 *
 * Purpose:
 * - Adds a simple visual separator field that renders as a horizontal or vertical line.
 * - One pack type "divider" with an 'orientation' property: 'horizontal' | 'vertical'.
 * - Inspector is Factory-driven (no WP templates). Preview is rendered by a pure JS renderer class.
 * - Keep defaults in 'schema' synchronized with JS get_defaults() in _out/divider.js.
 *
 * Contracts Used:
 * - Filter:  wpbc_bfb_register_field_packs
 * - Action:  wpbc_enqueue_js_field_pack
 * - Action:  wpbc_bfb_palette_register_items (optional palette registration)
 *
