/* ==========================================================================
   HALUHANA GROUP — Static Desktop Implementation
   ----------------------------------------------------------------------
   Scaling philosophy (revised):

   The reference PC design is a 1920px canvas, but the information that
   matters lives in a fixed ~1200px safe area (label 200px + main 890px +
   aside 110px) centered on the page. That 1200px zone — and every font
   size / component size within it — is NOT proportionally scaled down as
   the viewport narrows. Instead:

     1920px → ~1200px viewport:
       - the 1200px content zone stays a fixed size (px / rem)
       - only the OUTER MARGINS shrink (flex space, via minmax(0,1fr))
       - background/decorative elements (hero-bg-shape, hero-lines, the
         scattered circle/plus/triangle/equals marks) are fixed-size and
         anchored to the page edge, so they get naturally cropped by the
         section's overflow:hidden as the viewport narrows — they never
         shrink themselves
       - text sizes are literal px, never viewport-relative

     below ~1200px:
       - out of scope for this pass; layout will overflow rather than
         reflow until a dedicated responsive pass is done later
