   The tool-guide design system (docs/design/tool-guide-design-system.md) with
   the pairings grid right under the hero: a filter bar of pills, the cards in
   the guide frame, one-line stats, the lime bento, a four-step track, the dark
   card, FAQ, the other tools. The card classes (.pairing-*) keep their names so
   the copy / filter script stays simple.
