/* Keep Anchored — the umbrella site.
   Identity taken from the organisation mark: ground #111113, ink #fafafa. The
   page is dark-first on purpose — the mark was drawn for a dark ground and the
   products it points to are engineering tools, not consumer pages. A light theme
   is defined for viewers who force one, derived from the same tokens so nothing
   is left readable-in-one-theme-only. */
