/* Plenaria — Academic Conference Management
   (C) 2026+ C-MRiC | https://www.c-mric.com

   Plenaria palette, drawn from the arc-P logo mark: the deep purple of
   the stem and upper bowl (#4A2C82), the lavender of the lower bowl
   (#B3A0D6) and the paler lavender of the signal lines (#C9BEE0). The
   crimson accent (#E2001A) and the Poppins typeface carry over from the
   parent C-MRiC identity.
