Topographic Contours

Stacked elevation-map contour lines that breathe in and out like a slow survey map. Gives fintech, mapping, and B2B-data sections a technical backdrop without another gradient blob. SSR-deterministic SVG, zero JS.

Peer dependencies

None.

Theming

Colours come from the primary-* / accent-* Tailwind scales, so this drops into a project that is not Velocity without dragging our brand in. Install the contract once:

velocityx theme

Then set your whole brand in one place — raw RGB channels, not hex (a hex here silently breaks every opacity variant):

:root {
  --vx-brand: custom;
  --vx-primary-600: 220 38 38;
}

There is no component-level font-family anywhere in the library — your font cascade wins.

Licence

Commercial, for the duration of an active Velocity X subscription. The source is served by the licence-gated endpoint, never by the public CDN.
