/* =========================================================
   AILEARNIST — PLAYGROUND CORE (every ported playground page)
   The playgrounds keep their own component CSS (scoped under
   .pg-scope in tools/{slug}.css). This file maps their design
   variables onto the ailearnist / sqlism studio tokens so the
   playgrounds follow the site theme (light + dark), and
   restyles the shared surfaces (.glass panels, buttons) as
   sqlism-style studio cards. `.tool-page .pg-scope` gives these
   rules one extra class of specificity over the tool files.
