/* OpenEvo CCS Lab — shared design tokens.
   Canonical home for the CSS custom properties every static app in the ecosystem
   (conceptbase/app, and any future public static app) uses for surfaces,
   text, chart series, and status colors. Originally authored in conceptbase/app/css/
   styles.css (itself derived from the dataviz skill's validated default,
   references/palette.md), hand-copied into lab_manager/app/css/styles.css, then
   consolidated into openevo-graph/design-system/ on 2026-07-23, then lab_manager on
   2026-07-27. Moved here 2026-07-28 when lab_manager went private (internal-only
   dashboard) — openevo-core is the shared kernel repo, the correct public home for
   an asset every public-facing app in the ecosystem depends on.

   Tokens only — no component/layout rules. Each consuming app keeps its own
   layout/component CSS and just stops redeclaring this block.

   Theme is selected via [data-theme] (explicit toggle) or prefers-color-scheme
   (OS default) — the toggle always wins. */
