Playhead scrub SNAPS to where you drop it + soundfont rides the URL

PLAYHEAD — while live, retarget only GLIDED (never set playing), so a scrub moved the visual traveler but the audio slow-glided back toward the old spot.

SOUNDFONT IN URL — buildShareUrl adds ?sf= (non-default), and the chosen font restores from ?sf= (over localStorage) on load — a shared link brings its Pure Analog / Pure FM / GM font with it.

Verified: share-url PASS (13 checks); explorer-ui PASS (boot + live ride, zero errors — the targeting/starmap changes don't break playback).
