/* ============================================================================
   PULSE 3 : the shared design system for pulseai.studio
   Extracted from the "film" homepage candidate and raised to a full system.

   Language   cinematic photography with baked-in grades (overlay gradients, never a CSS
              filter on a large image), paper base, ink sections, one deep green block,
              one ember signal colour, Geist + Geist Mono, Newsreader italic on one word.
   Radius     pills for buttons and chips, 16px surfaces, 8px inner rows, 24px stages.
   Motion     transform / opacity / clip-path only. Custom curves only. Reduced motion = a
              complete static page.
   Grid       12 columns, 24px gutter, side margins clamp(20px, 5vw, 96px), content 1520px.
