/**
 * Yatra Page Content — block-editor registration.
 *
 * A dynamic, server-rendered block. PHP owns the front-end output via
 * Yatra\Core\Template\FseTemplates::renderPageContentBlock(). The editor
 * needs its own registration so the block:
 *   - Appears in the inserter / list view.
 *   - Renders a recognisable placeholder while editing a template.
 *   - Doesn't trigger the "Your site doesn't include support for the
 *     yatra/page-content block" warning when parsed from saved templates.
 *
 * No build step: this file is enqueued directly as a classic script that
 * uses the wp.* globals provided by the editor.
