/**
 * Quilt Block Templates and Primitives
 *
 * This module provides quilt block templates and primitive functions for
 * creating individual blocks. For grid repetition, use system.quilt().
 *
 * @example
 * ```typescript
 * // Use system.quilt() for quilts:
 * const quilt = system.quilt({ gridSize: [4, 4], blockSize: 100 });
 * quilt.every(2).placeBlock('BD');
 * quilt.every(2, 1).placeBlock('FS');
 * ```
