/* School Money — guides.css: guide articles, the free tools and the embeddable badge.
   Loaded after app.css on /guides/, /tools/ and /embed/ pages. Uses app.css tokens only (light and dark follow
   prefers-color-scheme there); nothing here sets a colour of its own. Every block shrinks to 360 px without
   horizontal scroll: grids use min(100%, …), flex rows wrap, and children get min-width: 0. */
