 * The Section Registry — the seam where Settings Sections are registered.
 *
 * The free plugin registers its core sections; Pro and extensions register
 * theirs via the `woocommerce_pos_register_settings_sections` action instead
 * of hooking ad-hoc filters. Registering an existing id replaces the previous
 * section (last-wins), which is also the supported override mechanism.
 * Override sections should extend Abstract_Section (not implement the
 * interface directly) so the typed accessors' default fallback
 * (Settings::section_value()) keeps working.
