Pure black (#000000). Not dark gray. Not near-black. Black. That commitment matters because the glass surfaces and glow effects only work against true darkness. The surface (#1A1A1A) is barely lighter. Cards are dark panels floating in void.

Inter for everything. Clean, geometric, invisible in the best way. The magic is in the details. At 1.714 type scale, headings are nearly twice the body size. Massive. The -0.96px letter-spacing on headings tightens them just enough to feel designed without feeling cramped. At 18px base size, body text is generous and readable against the black background.

A gradient text treatment (white to 50% white) on headings creates the illusion of text fading at the edges. Like words emerging from darkness. It's theatrical without being gimmicky. The text-to-background contrast is high enough for accessibility but softened by the gradient. Premium readability.

Glow hover effects on a black canvas are Blackmail's signature. Elements don't cast shadows downward (shadows are invisible on black). They emit light. A subtle indigo glow radiates from interactive elements on hover. Combined with the 0.98 active scale and smooth easing, interactions feel like operating a high-end audio interface. Precise. Weighted. Considered. The lack of traditional shadows forces every other design decision to work harder. And it does.
