/* Deutsch A1 · design system v3
   One source of design tokens for the public website (.lp-*) and the learner portal (.sh-*).
   Loaded after site.css / app.css: it also re-maps their legacy tokens so every page shares one palette.
   Shell and landing classes use their own --ui-* tokens, so pages with their own CSS (Wortschatz) cannot recolour them. */
