kasuti: four new motifs + custom pattern editor
Adds Rose, Totem, Figurine, and Snowflake to the motif reel — inspired by patterns 1/2/4 on the reference sketch and the red snowflake sample. Each is an Eulerian graph so an alternating tour exists (36/24/34/52 stitches respectively). Appends a "+ Make your own" tile at the end of the reel that opens a dialog-based pattern editor: click between dots on a 14×14 grid to toggle stitch segments. The editor reports connectivity and Eulerian status live and only enables "Use this motif" once the pattern is connected. The saved custom pattern is centered into the main grid and selected immediately. https://claude.ai/code/session_01KNdXjQczMCRGMK7K3Qderw
