   0.1 Base / Reset — 首页作用域版
   原为 Tailwind Preflight 的替身，写在 page-home.php 内联样式里。
   搬进 main.css 后必须限定在 body.jl-page，否则会波及博客/产品等模板
   （尤其 h1-h6 的 uppercase / font-size:inherit 和 ul 的 list-style:none）。

   位置：刻意放在 :root 之后、.btn-primary/.btn-outline 之前。
   原文件里 reset 在最前、按钮规则在后，reset 的
   "button,[type=submit]{background:transparent}" 特异性为 (0,1,0)，
   与 .btn-primary 同级，靠顺序决定胜负；若把 reset 放到文件末尾，
   会把按钮背景压成透明，提交按钮的蓝底会消失。

   作用域前缀一律用 :where() 包裹：:where() 不贡献优先级，
   因此加前缀后每条规则的特异性与原来完全一致，
   不会出现 "body.jl-page h1" (0,1,2) 反过来压过 ".jl-hero__title" (0,1,0) 这类问题。
