The floating drag copy hardcoded `maxLines = 1` on both its time label and its title, so picking up a block whose text wrapped clipped it to one line for as long as it was held, and it snapped back on drop.
- `DragCopy` now measures the range at its own width and height, exactly as the block does — same `MAX_TIME_LINES` cap, same spare-height rule.
- The block's measured title budget rides along on `TimelineDrag`, so the copy spends its height the same way the block did; the copy draws through `BlockTitle` now rather than a bare `Text`, so a wrapped title clips the way the block's does.
- That measurement moves into a shared `blockTimeLines`, which Week and Day each had their own copy of.
Deviation from the issue: it names only the time label, but the title had the identical hardcode and the two share one height budget — fixing the range alone would just have moved the mismatch to the title.
The copy still shows the range on a block too short to carry one; that is the feedback the drag exists for and is left as is.
