   synergy_apps.css  -  apps.synergyco.com.au
   Shared theme for the Synergy apps PWA (landing, login, logout).
   Single source of truth so the look lives in one place - avoids
   the copy-drift that hit calc-icons.css.

   Palette pulled from the Synergy Consulting logo:
     gold   #b8860b  (dominant leaf) - primary / led colour
     green  #00611a  (second leaf)   - secondary / actions
     red    #c0141e  (crescent)      - sparing accent / alerts
   Signature device: a thin gold->green gradient rule echoing the
   two crossed leaves of the mark.
