Fills {{column}} line templates per record (empty lines dropped, as for addresses), fits the text into the printable label area using font metrics and places every label at its exact millimetre position on sheets rendered by headless Chrome (scripts off, network blocked, full Unicode). Presets come from the gLabels template database (GPL-3.0, values unchanged; check them against your packaging); other sheets as a custom grid. Start position, copies, sender line, test outlines.
