A standalone portrait-first Logic Puzzle template.
SAMPLER
The quiet craft of counted cross-stitch, made playable. Read the counted-thread numbers on each row and column — each an unbroken run of one floss colour, in order — pick a thread, and lay glossy X-stitches into the Aida cloth until the picture appears; then mount it in the hoop. A colour logic puzzle on a real solver that proves every chart has one honest answer, so the title screen stitches its own masterworks and the demo is the regression test. Twelve motifs over three chapters — garden, folk, night — with a music-box score and chalk marks. Portrait-first, pure JavaScript, no build.

Light Grid Logic Remix
A **Lights Out** puzzle. Tap a bulb to **toggle it and its four orthogonal neighbours**; turn the whole grid off to clear the board. Order doesn't matter — *parity* does, so it's about *which* cells you press, not when. Undo and reset any time, and chase **par** (the number of presses the level was built from).

Ice Slide Logic
An ice-slide puzzle. Pick a direction and the skater **glides until a wall (or the exit portal) stops them** — there's no stopping mid-glide, so the logic is in planning which walls to carom off. Sweep over every gem, then come to rest on the exit to clear the level.
