/* ── Chat-widget for Boska Rør og Ventilasjon ────────────────
   Alt har prefikset br- så ingenting kolliderer med style.css.
   Fargane er sidas eigne variablar (med fallback til same verdiar)
   så widgeten følgjer sida om paletten blir endra. Boble, header og
   send-knapp går i primærblå. Radius ligg på 10–14px, litt strammare
   enn resten av sida, ingen gradientar eller glas-effektar.
   Stilarket blir lasta med media="print" og bytt til all ved onload;
   widgeten ventar på det før han legg seg inn i DOM-en. */
