/**
 * WPBC BFB Pack: Text Field (Schema-driven Reference)
 *
 * Purpose:
 * - Minimal, crystal-clear example of a field pack using Schema/Factory for the Inspector.
 * - No WP templates; preview is rendered via pure JS renderer class.
 * - Reference implementation to clone for other simple fields.
 *
 * Contracts Used:
 * - Filter:  wpbc_bfb_register_field_packs
 * - Action:  wpbc_enqueue_js_field_pack
 * - Action:  wpbc_bfb_palette_register_items (optional; used here to list Text in the palette)
 *
 * Notes:
 * - Keep schema defaults in sync with JS get_defaults().
 *
 * File:  ../includes/page-form-builder/field-packs/text/field-text.php
