Board notes 5 details

Layout: A three-layer shutter facade stacks a short top tier of orange shutters and pink cups above a middle band of white ring rollers and blue braces, with a larger lower wall of orange shutters hiding more pink cups behind the front face.
Goal: Pry open the right side so the top and middle bars spill out, then strip the lower shutter wall and the pink cups that stay hidden behind it.
Opening: Clip the upper-right white brace above the roller row and keep attacking the right-center seam around the rollers and rightmost lower shutter column.
Danger Zone: The left lower shutters and the untouched center are dead shots until the right seam has already peeled open and the rollers have started to spill.
Mechanics: A stacked shutter seam-peel board where the upper-right brace and right-center roller lane must open first so every lower layer can collapse in sequence.
