/* ============================================
   RILEY CHEN — PORTFOLIO
   Design concept: "Sticker Desk"
   A developer's desk covered in stickers, sticky
   notes and comic-panel cutouts — thick ink
   borders, hard offset shadows, spring-bounce
   motion. No blur, no soft gradients: everything
   reads like a physical object you could peel off
   the page.
