   Next Chapter Education: site stylesheet

   Company chrome keeps the original "contemporary crisp" system:
   warm off-white, near-black type, deep teal brand, red square
   marks, hairline rules, Outfit (display) + DM Sans (body).

   Product sections (.bb, .rr, .app-card--bb/--rr, .brand-card--bb/--rr)
   carry each app's own brand and mirror bookbright.app and
   realready.app.

   All fonts are self-hosted from /fonts. The privacy policy says the
   site makes no third-party requests, so keep it that way.
