/**
 * 「文章功能」后台设置页契约（对齐参考主题 1:1）：
 * 1) PHP schema（SchemaPostList.php feature section）字段键、顺序、默认值与
 *    JS schema（assets/admin/src/schema/sections/post-list/feature.js）一致；
 * 2) 参考主题字段全集存在：article_nav / article_nav_mobile_nav_s /
 *    imagelightbox / imagelightbox_type / imagelightbox_thumbs_s /
 *    imagelightbox_play_s / imagelightbox_zoom_s / imagelightbox_full_s /
 *    imagelightbox_down_s / post_like_s / post_default_mate(views/like)；
 * 3) 旧 AKSRT 私有/异名字段（feature_print / feature_pdf_export /
 *    post_lightbox* / post_like_enabled / post_default_*_min/max）已彻底移除，
 *    文章页面(page)不再承载这些字段，无双路兼容；
 * 4) 运行时（PostDisplay::get_post_page_settings）只读取新键，灯箱复选框
 *    pc_s/m_s 归并为开关，目录树与预置参数均接入运行时。
