/**
 * Templately "Post Comments" widget.
 *
 * Feature parity with Elementor Pro's Post Comments widget (source: current or
 * custom post, full native WordPress comment thread — avatars, nested replies,
 * reply links, pagination and the comment form, plus a "comments are closed"
 * editor notice). Unlike the Pro widget — which delegates markup and styling to
 * the active theme via `comments_template()` — this widget renders its own markup
 * and ships a base skin (matching the Templately Figma design) that is fully
 * customisable through the Elementor Style tab.
