Pluck Position

Which harmonics a pluck point kills, as pure maths: the comb response of the delay-and-subtract a Karplus-Strong exciter runs, the harmonics it silences exactly, the ideal plucked string's triangle shape and the spectrum that shape has, the integer-delay rounding a short loop actually realises, and laid-out SVG geometry for a string view and a comb plot. Pinned against a DFT of the shipped filter rather than against a restatement of its algebra. No React, no DOM — testable in Node and safe to draw with on the server.
