Leafstitch
Leafstitch is a standalone, mobile-first physical bookbinding defense roguelike. Begin on one complete thread spool, sew continuously through all six visible spine holes, and finish at the parked needle. Stable spool identity and the actual thread geometry resolve Link, Kettle, or Cross before a deterministic 80-node page solver advances thread tension, compression, moisture, paste diffusion and cure, grain curl, hinge opening, gilding, tears, and combat ward at 90 Hz.
