/* VoidCraft brand tokens + tiny reset.
 *
 * Every colour below is copied verbatim from assets/brand/brand.json ("colours").
 * Do NOT invent or tweak brand colours here — change brand.json upstream in
 * voidcraft-core, re-vendor (see assets/brand/README.md), then update this file.
 *
 * Usage rules that this stylesheet encodes (brand.json "rules"):
 *   - min mark size 48px            -> --mark-min
 *   - clear space >= 25% mark width -> --mark-clear
 *   - dark ground  -> colour mark   (mark-colour.svg)
 *   - light ground -> black stencil (mark-black-*.png)
