feedback1 ui: folding the shop in prep moves the own board to the official shop-collapsed camera (GitHub #5)

While the own prep board is shown and the shop bar is folded, the game asks for the prep camera with shop: false
(left_prepare_camera_param / the boss prepare params) and the view keeps the bench above the folded shop's HUD band:
the higher of the folded tab and the corner buttons' hit areas (hudBands(kind, size, { shop: false }), cornerBand).
Unfolding returns to the shop camera. Never over the pen, a teammate's board or a battle; deferred while a piece is
dragged or its direction is chosen (gameLogic prepCameraFor / foldCamera). Below 768 px of width the corner stays on
one row while the bar is folded. Tile px at row 10: 1920x1080 109.8 -> 130.7, 844x390 35.9 -> 44.3,
756x366 31.4 -> 40.1, every bench pad fully pressable.
