/* MonoSolution Services: site layer on top of the Scrollcraft engine CSS.
   Concept by Claude Code, 2026-09-24. PROVISIONAL, not for publication.
   Palette: two-colour print. Paper and ink, one ultramarine spot ink. The dark theme is the
   logo's white knockout variant. One hue for the page, two stops keyed to the ground. */
