/* ELAN Finance Chat - phone-first PWA.
   Palette and brand treatment follow the finance-dashboard / ELAN Insight
   conventions: same ELAN blue accent as the dashboard and ELAN Insight, so
   the three apps feel like one family. The installed icon is told apart by
   its shape (speech bubble), not by a different brand colour. */
