#090: Coral-Like Loop

I continue my exploration of [Wall]-Like Loop genres. I’m quite fond of the logic in this one. In particular, allowing unused cells outside of the loop but not inside leads to some interesting deductions I haven’t seen elsewhere.

Rules: Draw a non-intersecting loop through the centres of some cells. There cannot be any unvisited cells inside the loop. If there are number clues in front of a row or on top of a column, there will be exactly one line segment along that row or column for each clue with a matching length. The numbers are not necessarily given in order. A 0-clue indicates that there are no line segments along that row or column. Clues ignore line segments perpendicular to the row or column they describe.
