/* ============================================================
   SITE — DIAMOND, OBSIDIAN PALETTE
   Near-black ground carrying big ivory sheets. The mark's
   rotated square is the working unit: the four practices are a
   2×2 of diamonds you select from, markets interlock as a chain,
   bullets are diamonds. Motion grammar, three moves only:
   ARRIVE — a square turns 45° and becomes a diamond;
   SETTLE — tiles deal outward from the centre into the grid;
   CLICK  — a diamond takes a quarter turn when chosen or touched
            (a square looks the same after 90°, so only the turn shows).
   ============================================================ */
