/* ============================================================
   ConvergeQA — "Convergence" design system (shared)
   Concept: multiple AI perspectives converge into one documented review record.
   Signature: blue gradient. Premium, confident, trustworthy.
   Shared across app surfaces (Workspace, Account, Guided, Builder, Org, 2FA,
   Developers). Light + dark via [data-theme].

   USAGE: link this AFTER a page's own inline <style> so its token refresh and
   primitive components win the cascade:
     <link rel="stylesheet" href="/static/convergence.css">
   It intentionally does NOT include a global `*` reset or page layout — only
   design tokens, base typography, and reusable component primitives — so it
   refreshes an existing page's look without disturbing its structure.
