Harbor Lines Strategy Set · Night Signal is a curated tabletop game prepared for the Collectorium T launch selection. The set was conceived for repeated table use, with an immediately readable system and pieces that acquire character through play.

Its visual identity combines cloth play mat with enamelled metal markers, a cobalt, ivory and aged copper palette, and a rolled rectangular cloth field with a fitted box. Recorded display dimensions are 40 × 40 × 5 cm boxed. The gallery documents small discoloration at one edge and intact construction; unmarked surface with hand-finished tool traces. Each image is a separately composed camera view of the same presentation piece. This presentation record is informational only; ownership, maker attribution, certification, scarcity and provenance verification are outside its scope.
