How long the row/mesh highlight stays before auto-clearing.

Auto-classify all bodies in a part as welds if the majority are already welds. Applies on next file load.

rev34: prints the per-mesh PAIRING LIST and ROW LIST dumps to the console after each 3D load. Off (default): one compact pairing summary line instead, so console pastes stay small. The placement DIFF and the label-free PLACEMENT VERDICT always print regardless of this setting.

Experimental: tessellate each BREP body from its own tagged mini-STEP instead of the whole file. Identity-based mesh mapping with exact per-instance placement, progressive loading.

rev28: the STEP file can mark geometry invisible (INVISIBILITY / presentation layers). Off (default): shard mode SKIPS tessellating those bodies, saving compute; their rows stay in the tree and the eye toggle explains how to include them. On: they are tessellated but still start hidden (the eye toggle shows them). Applies to shard mode; whole-file mode always tessellates everything. After changing this (or the mesh quality), press Force Re-tessellate to apply without reloading the file.
