/*
  The 首页, 笔记 list and reader screens: the landing hero, the post cards, the
  search box and the article. Loaded after base.css, which holds the design system.

  These rules are NOT scoped to a screen, so anything named here that the 播客 screen
  also uses (.hero, .intro) reaches it too — which is why podcast.css restates those
  two under .podcast. Prefer a name this file owns over adding to that overlap.
