Tap the field to drop points, drag them to adjust, double-tap one to remove it.
Draw from only changes where you stand while drawing — it isn't saved with
the concept. The faded copy is the same route mirrored to the other side of the ball.
Saving under an existing name replaces it, and every play running that concept picks
up the new shape. Rename it first to save a copy instead and leave the original alone.
Publish to the team site
Publish takes the concepts published on GitHub, applies this browser's changes on top,
and commits js/route-concepts.js — so it only touches concepts you've edited
here and never overwrites work published elsewhere. Same token as the Play Editor.
