/* ═══════════════════════════════════════════════════════════════════════════
   FIELDCHAT WIDGET OFFSET — PLAYGROUND PAGES
   ─────────────────────────────────────────────────────────────────────────
   The fieldchat widget uses --fc-top-offset to know where to start its
   bottom-sheet on mobile. Playground pages have two stacked navbars:
     • Site nav (≈ 60–64px)
     • Workspace nav (.pg-workspace-nav, 48px)
   Total ≈ 108–112px.

   Using :root:has(.pg-workspace-nav) means this only applies when the
   workspace nav is actually rendered on the page. Pages without the
   workspace nav fall back to the default 60px defined in ask_ai.css.
   ─────────────────────────────────────────────────────────────────────────
   Browser support: :has() is supported in Safari 15.4+, Chrome 105+,
   Firefox 121+. Older browsers fall back to the 60px default gracefully.
