/* ============================================================
   TECH ART PORTFOLIO — design tokens
   Concept: a DCC viewport / G-buffer readout, not a marketing page.
   Flat panels, hairline rules, sharp corners, no drop shadows.
   Accent colors are drawn from real buffer-visualization hues:
   emissive-orange (shaders), LUT-teal (post fx), GI-violet (ray tracer).
   ============================================================ */
