Replace the 0.2.1 enclosure recording with a 40 s take of the current desktop UI building a Raspberry Pi 4 case: a sketch dimensioned with the board's parameters, extrude, fillets and shell, an M2.5 standoff patterned on the 58 x 49 mm hole rectangle, port cut-outs, floor vents, a colour, then height 24 -> 32 mm in Parameters. The demo script gains the pi story (now the default). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
