formatMeasure checked the raw length against 1000 but printed it rounded, so a drawn line of 999.5 m or more read "1000 m" in the hint. Compare the rounded metres so it moves to kilometres.
Supersedes #235 by @cora-fresh-labs, ported onto the current component layout with fixes from review.
Verified before merge: format, package boundaries, unit suite, build, and the browser tracking suite; a browser harness for the change where one applies; adversarial review applied.
Future work (not in this PR): hand-drawn marks do not persist across a reload today, and neither do spoken annotations; there is no storage layer for marks. The natural home is Scenes: a drawing that belongs to a shot and persists per shot, so a scene animation can carry its own marks. Needs an owner.
