"""FTs for the My Sea standalone page sign-gate.

Sprint 4b of [[project-my-sea-roadmap]]. The /gameboard/my-sea/ page is
gated behind sig selection — when `user.significator` is None, render a
Look!-formatted Brief-style line w. FYI (→ /billboard/my-sign/) + BACK
(→ /gameboard/) instead of the draw UX. The My Sea applet on /gameboard/
mirrors the gate hint in its empty-state slot.
