   4D Creative Studio — main.css
   Design direction: dark editorial studio. A photographer's contact sheet
   meets an architect's blueprint — hairline grids, frame-corner marks, and
   a viewfinder cursor tie the "web design + photography" brief together.
   Type: Bebas Neue (display) / DM Serif Display (editorial serif, italics
   for accents) / Space Mono (labels, numerals, utility).
   Palette: near-black ground, warm champagne-gold accent, bone-white ink.
