Controls are 40px tall with 12px 20px padding and a full 9999px pill radius, while cards are a hard 0px. Primary is #ffffff on #000000 text, inverting to #000000 on hover — an unusually high-contrast hover for a dark site. Disabled is opacity .5.
Specimens use Space Grotesk (for PP Neue Montreal) and JetBrains Mono (for GeistMono) — the real faces are licensed. Note that tracking opens to +0.24px at small sizes rather than tightening.
There is no shadow scale — the only box-shadow on the site is a transparent ring reset. Depth is these four flat bands separated by 1px #202022 hairlines. No gradients, backdrop-filters, canvas or video were found anywhere. Motion: 0.15s cubic-bezier(.4,0,.2,1), with keyframes that are functional (marquee, accordion, caret-blink, shimmer) rather than decorative; one prefers-reduced-motion block is honoured.
