/* 品牌文字块。
   ⚠ 本 bug 的完整定位链（勿回退）：
      现象：块高 52.4px，实际内容仅 33px（.name 19.8+ .sub 12.6 + 间距 2），
            底部多出 18px 空白 → 几何中心对齐了，视觉上却没居中。
      试过且**无效**的方案：改 line-height（→52.4 变 49.5，量级不对）、
            align-self:center、flex:none、gap/margin 调整、块改 grid、.brand 改 grid/block。
      二分实测定位：块显式 height:34px + flex 列 + justify-content:center → 高度变 34px ✅
      根因：.name/.sub 作为块级子元素继承 body 的 line-height:1.65（约 29.7px），
            行盒高度远超实际字高，两行叠加后多出 18px，且位于底部。
      对策：给块一个与图标等高的固定高度（34px），用 flex + justify-content:center
            让两行文字在块内居中。固定高度同时规避了行盒残留问题。 */
/* 品牌文字块 —— 垂直居中修复（勿回退）。
   现象：文字中心在y=22，顶栏中心在 y=31，偏上9px，视觉上没居中。
   排查过的无效方案（高度恒为 52.4 或居中不生效）：
     align-items:center / flex:none / justify-content:center /
     gap / margin / align-self /块改 grid(align-content) / 块改 block。
   实测有效解法（三者对比）：
     块 display:flex + justify-content:center  → 中心 22  ❌
     块 display:grid + grid-template-rows:1fr 1fr + align-items:center → 中心 31.2  ✅
   原理：行高1.1 下两行文字的**行盒**在 flex 均分时仍按内容高堆叠在顶部，
   grid 的 1fr 1fr 会把34px 明确二等分，配合 align-items:center 才真正居中。 */
