/* Sync2VA Connect: dark glass over the Sync2VA artwork.
   Two lights, as in the logo: Volt blue and Ember orange. Blue is "you" and the app's actions; orange marks staff and
   what needs attention; green only ever means "here now". Glass panels let the artwork show through, but messages
   always sit on a solid enough surface to read on a phone in the evening. Titles in Fraunces, messages in the
   phone's own font. */
