/* not6741.lol — shared styles
   ------------------------------------------------------------------
   This file holds the design system: tokens, base elements, nav,
   buttons, panels, footer, scroll-reveal and the floating bits.
   Anything used by more than one page lives here.

   Page-specific rules (the hero, the terminal, the project cards,
   the skill popup) stay inline in each page so they only download
   where they are actually needed.
