Built from Spectalpack's KLD conventions (seal & safety-margin defaults, gusset fold logic, zipper/notch clearances) — adjust any of them under Conventions & allowances if a job needs something non-standard. Quad seal isn't wired up yet — send over a sample KLD or the panel breakdown and it'll get added.
