/*
  explainer.dk – site styles on top of Basecoat (https://basecoatui.com).
  Basecoat's CDN bundle ships Tailwind's base + Basecoat components, but no layout utilities,
  so layout lives here. Everything uses Basecoat's design tokens (--background, --border, ...).
  Styles are placed in Basecoat's cascade layers so Basecoat components keep working.
