/* ========== 协议强调样式（手动套用）==========
 * 用 <span class="类名"> 包裹要强调的文字，类名可任意组合：
 *   <span class="t-bold">加粗</span>
 *   <span class="t-red">标红</span>
 *   <span class="t-underline">下划线</span>
 *   <span class="t-red t-bold">标红 + 加粗</span>
 *   <span class="t-red t-bold t-underline">标红 + 加粗 + 下划线</span>
 * 一键三连（红 + 粗 + 下划线）：
 *   <span class="t-stress">重点内容</span>
 * 也可直接加到现有标签上，如 <strong class="t-red">、<p class="t-red t-bold">
