/* ═══════════════════════════════════════════════════════════════
   OL-UI-000001 — Oleren Learn design system
   ───────────────────────────────────────────────────────────────
   WHAT:  Every token, component and motion rule for the platform.
   WHY:   Hand-authored rather than generated. A utility framework
          would add a build step for the customer and push the
          design toward a recognisable default look. This file is
          ~20KB, ships compiled, and needs no toolchain.
   NOTE:  No inline styles are used anywhere in the platform, so the
          Content-Security-Policy can stay strict. Anything dynamic
          is expressed as a class or a custom property set here.
          See OL-CORE-000004.

   WHAT:  Cross-document transitions via the View Transitions API.
   WHY:   Gives the platform its sense of continuity between pages
          without a single-page application. Browsers without
          support simply navigate normally — there is no polyfill
          and no JavaScript cost.
   NOTE:  The style is chosen in settings and applied as a class on
          <html>. 'none' opts out entirely, as does any visitor
          with reduced motion enabled.
