The background is warm cream (#FFFDF5) with a yellow undertone. Not pure white. That warmth is subtle but essential, because the electric yellow accent (#AF9100) lives against it. Pure white would make the yellow garish. The cream keeps everything in the same warm family. White surface cards pop cleanly against the warm background.

Plus Jakarta Sans at weight 800 for headings. Extra-bold. Thick, geometric, and loud. At -0.03em heading tracking, those letters compress into something that demands attention. This isn't a font that asks permission. It fills space and holds it. The 1.1 heading line height keeps the massive type tight and impactful.

Body text drops to weight 400 with 1.6 line height and stays clean and readable. Jakarta Sans has this quality where the bold weight is a completely different personality from the regular weight. Heavy and geometric up top, clean and approachable in the body. Same family, two different energies. Space Mono for code adds structured contrast when you need technical credibility alongside the boldness.

Yellow-tinted shadows. 4px 16px at yellow rgba with a secondary soft black layer. Cards feel like they're sitting in sunlight. No dark, heavy shadows. This is an optimistic system. Depth is created through color contrast (white cards on cream background) more than shadow weight. The bouncy easing curve (0.34, 1.56, 0.64, 1) gives the scale hover effect a springy, energetic feel. Active scale at 0.95 provides satisfying tactile feedback. Smooth motion means nothing happens too fast or too slow. The entire atmosphere says "click me, something good will happen."
