White background, but the surfaces aren't gray. They're tinted. That's the entire personality of Bubble in one sentence. The borders (#D0CCED) are lavender. The muted text (#6E6493) is purple-gray. The main text (#1A1139) is deep purple-black, warmer and more interesting than pure black. It takes the standard light theme formula and shifts every neutral toward violet. The effect is immediate. The interface feels alive and intentional instead of default.

DM Sans for everything. Headings and body. It's a geometric sans-serif with a natural warmth that comes from its slightly rounded terminals. At weight 700 with -0.03em heading letter-spacing, the headlines are confident and clear. Not shouty. Not aggressive. Just present. The letterforms complement the generous 20px radius throughout the system. Round type inside round containers. Everything is part of the same family.

At body weight 400 with 1.6 line height, DM Sans drops to a clean reading experience. It has that rare quality of being personality-forward in headings and invisible in body text. Same font, two completely different jobs. Space Mono for code adds utilitarian contrast when you need it.

Purple-tinted shadows. Not black, not gray. Purple. The primary shadow (4px 20px at rgba(108,71,255,0.08)) means depth feels integrated with the color system instead of bolted on. Cards float gently with a violet mist beneath them. The bouncy easing curve gives every scale hover effect a springy, delightful feel. Smooth motion speed means transitions breathe. Active scale at 0.95 gives tactile feedback on press. The whole depth system reinforces the playful, colorful personality. Even the ring focus style uses the violet accent. Everything is purple. That's the point.
