   OgbonLab, Code Playground v2 styles
   --------------------------------------------------------------------------
   Phase 2 of docs/code-playground-v2-engineering-plan.md (§3).
   Scoped under `.cpv2-shell` so v2-local tokens don't pollute OgbonLab
   globals. Anywhere outside the v2 surface, this file is dormant CSS.

   When Code Playground v2 is the default and v1 is deleted (post-Day-14
   cutover, mirroring AI Tutor v2), this file can be promoted to load
   unconditionally without changes, the .cpv2-shell scope is the
   intentional containment boundary.
