/* ==========================================================================
   LLaDA-UI project page — charts.css
   Results section: domain tabs, bar-chart cards, radar card, tooltip,
   comparison tables (also used by the lazily-loaded partials).

   Bar identity follows the report's own convention: LLaDA-UI = indigo,
   other diffusion models = warm mask tint, autoregressive models = slate.
   Identity never rides on color alone: every bar is direct-labeled and the
   full tables sit below each chart group.
