/* librarëtte — shared site system. One palette, one voice, no legacy green.
   This is the CANONICAL design system for the whole site: the native
   librarëtte pages, the Pond field guide, and every migrated FROG labs/demo
   tool all load this file and build on these tokens. Dark charcoal ground,
   light ink text — every page keeps that polarity throughout (no "white
   card" sections), which is what makes one shared system possible across
   pages that used to come from very different sources. */
