/**
 * DEEP SEA: the members' boat trip from the King's Harbour (James, 2026-10-04, W-093: "Start Deep Sea next, the second
 * Crown tank: a members' boat trip from the King's Harbour with deep-sea catches for a Deep Sea book page"; plan
 * `.cursor/task-plans/2026-10-04-deep-sea.md`).
 *
 * Skipper Gale Hollis keeps a berth at the head of the harbour's North Pier (harbour.ts HARBOUR_NORTH_PIER). For a fare
 * a member is taken out to the Grey Gannet, a fishing boat anchored over Gannet Deep in the north sea, and has ten
 * minutes on her deck (a timed run, timedRun.ts 'deep-sea': the clock runs through a logout). With the sea tackle the
 * conger and the sea bass take (a Heavy Beach Casting Rod, line, hook and float, lugworm or a spinner) the deep gives
 * three fish: the Ling, the Halibut and, rarest, the Anglerfish. Deckhand Pip takes anyone back early; when time is up
 * the Gannet runs back to the berth.
 *
 * The three are members' catches, so they are bonus specimens in the aquarium book (aquarium.ts): they fill its Deep Sea
 * page and the Capital Aquarium's Deep Sea tank for members and never block a free player's book or title.
 *
 * World tiles, absolute. Backend: deepSea.ts (the boat's deck and pieces, after the harbour is built) and world.ts (the
 * trip). Blender pieces: quest-workshop/scripts/deepsea_v00N.py (dsgannet, dsboard).
