/* 3D Flipbook Studio (extension package). The modal chrome (backdrop,
   frame, header, footer, close, buttons, selects, scrollbars) comes from
   the editor's own modal design (dsm family) - the dialog mounts inside
   #wpie-root exactly for that. Only studio-specific layout lives here
   (prefix wpiefb- so sibling studios never collide). The three column
   body, the settings cards and the checkered view mirror the 3D Gallery,
   Text and Mockup Studios. */
