Pure black. Not near-black, not dark gray. #000000. That's the most committed dark background possible. The surface at #1A1A1A is barely lighter. The whole interface lives in a narrow band of darkness, which makes the blue accent (#3131FF) explode with energy. That deep blue is darker than most UI blues. It's almost indigo. On pure black, it reads as electric and intentional.

Inter at weight 500 for headings with 0.4px positive letter-spacing. That outward spread creates titles that feel spaced and deliberate. Not compressed and urgent. Measured. Like keyframes on a timeline, each character has its position. The 500 weight keeps headings substantial without going bold.

Body text at weight 400 with generous 1.6 line-height gives content room to breathe inside those heavy-bordered containers. The white text on pure black has maximum contrast. The line-height prevents that contrast from becoming fatiguing over long sessions.

No shadows. On pure black, shadows are invisible anyway. Keyframe doesn't pretend otherwise. Depth comes from the border weight and surface color stepping. The fast motion speed and custom easing curve (cubic-bezier 0.12, 0.23, 0.5, 1) create snappy interactions that feel like scrubbing a timeline. Every state change is precise and intentional. Like animation software should be.
