Subject: [PATCH] PM_K-1 grid: smaller circles + align beats vertically across
 lanes

Place step circles by proportional position in the bar (beat = column start) instead
of centring in per-lane slots, so same-meter lanes' beats land at the same x (e.g. the
8-step hat's beats sit directly under the 4-step kick/snare). Cap circle radius at 6
(was up to ~18). Verified by printing per-lane beat x-positions + rendering the grid.
