Create a standalone portrait 9:20 onboarding reference matching the supplied Foldwake gameplay master. Source refs: SCR-ONBOARDING, ST-FRESH, M-FOLD, M-PREVIEW, E-BOAT, E-HARBOR, E-CREASE, ENV-CHART, UI-CREASE-RAIL, UI-PRIMARY, A-COLOR, A-MOTION, V-FOLD. Show only a calm two-cell cream-edged paper chart on indigo: one amber lantern boat with triangle glyph on the upper cell, one teal ring harbor with matching triangle glyph below, and a large cyan dashed crease with a ghost hand-arrow showing the one legal downward fold. Use one short readable instruction: “Fold the boat onto its harbor.” Include small Skip and accessibility icon, ample safe areas, no carousel, no extra entities, no rewards, no shop. Same cut-paper materials, palette, icon strokes, and orthographic camera as the master.
