/* ============================== Custom Electrics CRM — design tokens ==============================
   Palette sampled from the real Custom Electrics Ltd logo (deep teal ring + terracotta accent on a
   pale mint ground). This file is the one place trade-specific branding lives visually — a future
   deployment for a different trade swaps this file (and the wordmark markup in the header) and
   nothing else in the layout needs to change. */
