// Tapo Ceiling Mount - Assembly Preview
// ============================================
// Non-printing preview of the whole system:
//   ceiling, upper clamps, exterior plate, connector collar, camera adapter,
//   approximate camera, Ethernet cable, DC cable.
//
// Modes:
//   assembly_mode = "assembled"  full stack in place
//                 = "exploded"   parts spread along z
//                 = "section"    assembled, cut on the y=0 plane for the cables
//
// Colors show only in the interactive preview ($preview). Printable parts do
// not depend on color.
