/* =====================================================================
   Mentoza — feature chapters: the real product screens, interactive
   ---------------------------------------------------------------------
   Each chapter visual is a browser window running the real Mentoza UI
   (css/product.css, scoped under .pui) plus a few landing-page helpers
   around it (student phone, quick palettes, float cards).

   The product pages render with CSS `zoom` inside the window, so each
   window shows the product's own responsive layout at a believable
   viewport width, crisp and readable. Chapter-only layout overrides
   (palette inline, room side panel inline, two-column branding…) live
   here, never in product.css.
