/* ==========================================================================
   Ontology Function Panel (M14)
   --------------------------------------------------------------------------
   function-panel.js 动态创建 DOM，使用自定义类 + 少量 Bootstrap 风格类。
   本应用基于 Tailwind（无 Bootstrap），因此这里为该面板补齐全部样式。
   所有选择器都限定在 .ontology-function-panel 作用域内，避免污染全局。
   布局与 action-panel/version-panel 等兄弟面板一致：右侧固定抽屉（420px 宽）。
