   tool_ui.css v1 — 2026-11-09
   /sun（日出日落）与 /wc（风分量）专页 UI 优化
   ----------------------------------------------------------------------------
   设计约束（与既有工程约定一致）：
   1. 样式全部外置，页面片段内不写 <style>；片段由 web.py 的 html % (...) 格式化，
      片段里出现任何裸 % 都会抛异常。
   2. 本文件只作用于 .calc-page 作用域，不影响 /tool/calculation 的 v1~v7 布局。
   3. 不改动 calc_ext.js 依赖的任何 id / name，计算逻辑零改动。
   4. 移动端断点与全站 header.css 保持一致（1023px），并禁用 hover 位移。
