   book, ticket and tables scroll inside their own panels (thin, muted scrollbars).
   Scope: embedded + signed in + Trade route, i.e. #app.signed-in > .main[data-route="trade"] (body[data-route]
   stays "trade" after sign-out, so it is not used). Applies to frames 901 px and wider, and to 600-900 px wide
   frames at least 860 px tall (tablet portrait). Other narrow frames (phones) keep the scrolling mobile layout.
   Other routes and the sign-in page are unchanged: they scroll with the hidden scrollbar above.
   Browsers without :has() skip the whole block and keep the previous (scrolling) layout. */
