A path ends with the unit turned to the packet's final facing, as 1.12.1 leaves it.
- A monster move that installs a path stores its final facing on the spline (`0x618840`-`0x6188a0`). Only a move with no path turns the unit on arrival.
- At the path's end, `0x61a882` writes the facing in this order:
- Angle, as sent;
- Target, the heading to where that unit stands (`0x61a8c1`), from the deck-local end on a transport;
- Spot, through `0x47f220`.
- The turn runs through the facing smoother (`0x600cd0`), never a snap. The display facing resets only at create and reactivate.
- `heading_between` ports `0x47f220`'s fixed headings for a point under the unit.
Each change has a test that fails without it.
