How this board opens
A first sweep of the overlap rule down the rows and across the columns settles 98 of the 225 cells, about 44%, which is enough of a skeleton to work outwards from. The most generous opening is row 10, which gives up 15 cells on its own. 3 of the 30 lines are decided outright by their clues, with no room to slide. Straight line logic carries it to 174 cells and then stalls, so the last 51 need cross-referencing between a row and a column that share a cell. The finished picture fills 83 cells, and one run in the clues is 15 long — near enough the full span of a line that it fixes itself the moment you reach it.
