"""Seed the My Sign (a.k.a. My Significator) applet on billboard.

Sprint 4 of the My Sea roadmap. "Significator" remains the storage-layer
term (User.significator FK, room sig-select) — this billboard surface is
branded "Game Sign". 4×6 (narrow + tall), seeded after all other billboard
applets so it renders at the end of the billboard grid. Shows the user's
saved significator card or a blank state.
