   Shared styles for /solutions/ and /solutions/<slug>/.

   Depends on: tokens.css, base.css, partials.css.
   Reuses: tier-section-head and faq-list from pages/tier.css when
   loaded together. Solutions sub-pages do not load tier.css; the
   small handful of common bits are duplicated here intentionally.
