   LyraMind: the design system.

   Every page previously carried its own private copy of a slightly different
   design: serif headings here, a different blue there, four separate navs. That
   is why the site read as several products. One stylesheet means a change to the
   homepage look propagates everywhere instead of needing fifteen edits, and it
   is the only way the pages stay consistent as they are rewritten.
