/* h-dash stylesheet.
 *
 * Colour is declared once, as custom properties, in two blocks: light and dark. The
 * SVG marks carry class names (`s1`…`s8`, `grid`, `axis`) and resolve their fill and
 * stroke from those properties, so a theme change is a variable swap rather than a
 * second rendering path on the server.
 *
 * The values are the validated categorical palette from the repository's
 * data-visualisation guidance. Slots 1–3 (blue, orange, aqua) are the set cleared for
 * every pair in both modes, which is what the Baltic zones use. Dark is a selected set
 * of steps for the dark surface, not an automatic inversion of light.
