/* Briary PV suite.

   The application shell — head, bar, three-column layout, result panel, rows
   and modals — is the one the window U-value calculator uses, so this sheet
   only adds what is particular to the PV workspace: the step list, the drawing
   area, the modal form grids and the plane table. Load it after
