   LINE 板块样式（第 9 刀 CSS 拆分 · 最后一刀）
   从 style.css 拆出。core(style.css) 先加载，本文件后加载。

   ★ 故意留在 core（共享/全局/变量，未移入本文件）：
   - :root { --line-* } LINE 配色变量 —— 本文件引用它们，变量定义须留 core
   - 聊天基础设施（6 板块共享，按铁律留 core）：
     chat-list-container / chat-item / chat-avatar / chat-info / chat-name /
     chat-preview / messages-container / message / message-bubble /
     message-avatar / message-actions / msg-action-btn / chat-input-glass /
     voice-* 全族（语音泡）—— 被 tutor / worldbook / writer / forum /
     mail / twitter 共用（grep js/+index.html 实证）
   - send-icon-btn 主定义（line+forum+tutor 共享）及其 line-green 覆盖
   - .message-avatar.hidden-avatar / .message.system.summary-message（共享/全局）
   - .modal-title-icon（通用 modal 标题图标，高复用潜力）
   - @media(aspect-ratio:1/1) 内 .line-tab-* 响应式（跟全局壳一致留 core）
