Design system

The actual tokens and components this site is built from. The idea is a data lake at depth: deep teal-black water, lake-teal accents and a lime "signal" for anything live or active. Light theme is an equal partner.

Colour

OKLCH throughout. Both themes keep body text at 7:1 or better and muted text at 4.5:1 or better against their backgrounds. Lime is a fill and highlight, never long-form text on white.

Typography

One family, stretched: Archivo at width 125 for display, at width 100 for reading. JetBrains Mono only for genuinely technical metadata such as dates, stacks and commands.

Spacing and shape

Fluid spacing with clamp(): tight inside groups, generous between sections. Corners use a 14px radius, and pills for chips and buttons.

PressedPressed / selected: ink fill

Try it: press Tab to move through the controls above and see the real focus ring.

Easing: cubic-bezier(0.22, 1, 0.36, 1) (ease-out-quart). No bounce, no elastic.
Purpose: motion shows flow (data streams, highlighted paths) or responds to input. It never gates content visibility.
Reduced motion: under prefers-reduced-motion, animations and transitions collapse to near-instant and the hero canvas draws a single still frame.
