/* The tool demos (onboarding/partials/_tool_demo.html, played by
   onboarding/js/tool_demos.js): one tool's slice of the homepage's pine
   coach band, also the "See an example" dialogs. The slice lays itself out
   by its own width (a container query), so the band and a dialog share one
   set of rules. Every class starts td-, clear of the site's own (.bar, .sev,
   .tag...). Approved mock: docs/mocks/homepage/round3/homepage.html. */
