/* ---------------- Mobile / responsive ----------------
On phones the fixed 396px sidebar can't sit beside the 3D, so the rail
becomes a bottom sheet that starts collapsed (only its handle + price peek
above the fold) and slides up when tapped; the 3D fills the whole screen.
The toolbar moves to the top so the sheet never covers it. Touch orbit +
pinch-zoom in the 3D are handled by the engine's camera touch script. */
