+"""Seed the My Sea applet — Sprint 3 of the My Sea roadmap.

+The applet itself is just a shell for now (header + horizontal scroll
+container w. empty-state placeholder). Sprints 4+ will fill in the
+sig-select / sea-select / gatekeeper phases that render in the dedicated
+`my_sea.html` page reachable via the applet's header link.
+
+Grid: 12 cols × 4 rows — wide horizontal banner so the latest draw's
+10-card Celtic Cross spread can render left-to-right in the applet
+aperture, scrollable like My Palette.
