/* semurg-ic.css: the ONE stylesheet for one.semurg.io.
   The IC deck's design system (investment/ROOM/IC_PRESENTATION/src/ic.css) carried to the web: same tokens, same
   hexagon motif, same card / stat / table / bullet forms. The deck is print (mm, fixed slides); this is fluid and
   works at 1280 and 390. WHITE ground, BLACK type, red #DE3122. No auto-dark, no system-font stack, no legacy accent.
   One file: a page adds no stylesheet of its own. */
