 * Sundered Coast's north beach (land from z 917), east of the Sundered Span. Decoration only, like the beach loop: no
 * transport, combat, discovery or quest.
 *
 * The inshore leg is the plan's line, sailing west along z 900 from x 914 to x 700. The return leg is in the open
 * strait 8 tiles north, at z 892, sailing east. The turns are tight on purpose: a 17-tile hull swinging round a wide
 * turn sweeps its bow and stern out over the shore, and here the mainland is 11 tiles off the return leg, the Span's
 * landing (water from x 686) 14 tiles west of the lane's end and the map's edge (x 928) 14 east of its start. So the
 * west turn reaches x 697 and the east one x 918, and the whole hull keeps a tile of sea round it everywhere
 * (frontend scripts/sea-traffic-route-test.ts; backend scripts/south-expansion-smoke.ts against the built world). It
 * never goes south of z 900: Fort Rook (z 990 on) and the cove are the far side of the coast.
