 * - Leaders (`brush: true`) publish via `publishBrushRange` and do not follow.
 * - Followers mirror the active leader range unless `syncFollower` pins a leader id.
 * - Multiple leaders: last `publishBrushRange` wins (same as cursor `publish`).
 * - Panels never follow their own `syncId`.
 * - Empty or degenerate published ranges are ignored (followers show full data).
