The px-per-mm mapping was a hard-coded guess twice over, and the right value depends on the monitor - AutoCAD has the same knob as the Adjust Display Scale slider. Expose it: a slider plus a number box next to the lineweight toggle, with a readout of what the drawing's own weights come out to (0.35mm -> 7px, 0.50mm -> 10px at the 20 px/mm default). The value persists in localStorage. Retuning applies to the live materials instead of rebuilding the scene. The hairline cut-off is a millimetre value, so changing the scale moves every weight by the same factor without changing which bucket a segment belongs to - each fat batch now remembers its weight in mm, and only material.linewidth is rewritten. That keeps a drag on the slider instant even on the 37 MB road drawing. Measured headless on its 0.35mm gutter line: 2-3px at scale 8, 7px at 20, 14px at 40 - matching the readout in each case.
