/* artifact_panel.css — 通用右侧 artifact 面板（14 §6.3）
 *
 * 定位：作为 .preview-panel 内的兄弟容器，与 #pvPreview（deck 预览器）
 * 及各 overlay（search/image/parse/sub-agent）共存。共存规则（§6.3 末段）：
 * 当前会话有 deck 产物（#pvPreview .page-card 存在）时本面板隐藏，
 * deck 预览器优先；deck 无产物且后端推 render_intent 事件时本面板显示。
 *
 * 窄屏（<900px）折叠为隐藏 + toggle 按钮（§6.3 "窄屏折叠为消息流内卡片"
 * 简化版：仅 toggle 显隐，不做卡片流）。
