/* isdem.org — single-page "less is more" landing site.
   Palette and mark colors come from the institute's own logo (three
   overlapping timing-distribution curves): navy, slate, grey-blue.
   The Plenary/Current focus/Published block lives in a differentiated
   "noticeboard" panel beside the main column (stacks above it on mobile),
   set apart with a warm neutral surface so it reads as a callout rather
   than body content. */
