Light blue-gray background (#F8F9FC) instead of white. It's the color of morning fog. Cool, calm, and spacious. White card surfaces pop cleanly against it. The text color (#222222) is a warm near-black that's softer than pure black. The purple accent (#574CD5) is rich and saturated. Not pastel. Not muted. Full-strength purple that creates energy without aggression.

Inter at weight 500 for headings with extreme letter-spacing (-3.4px). Very aggressive compression. Headlines feel like they're sprinting across the page. The letterforms compress into a single visual mass that reads as kinetic. Movement in stillness. For an athletic brand, the typography should look like it's going somewhere.

Body text at weight 500 is heavier than standard. The whole typographic system leans bold. Even the body feels assertive. The 1.4 line height is slightly tight, which reinforces the active, energetic feeling. Nothing in this system lounges. The 1.2 type scale keeps size steps subtle. The emphasis comes from weight and spacing, not from dramatic size differences.

No shadows. Depth comes from the surface color contrast (white cards on blue-gray background) and the dramatic glass effect. The 40px blur at 0.2 opacity is a wide, gentle frosted glass that turns background content into soft shapes. It's atmospheric and environmental. Like trail mist. The glow hover effect adds purple warmth to interactive elements. Combined with smooth motion, the interface feels like it's breathing.
