 * 请根据您的使用环境提供一个 50x50 的 2D Canvas 上下文
 * @example
 * // Node.js + canvas
 * import { createCanvas } from 'canvas'
 * const canvas = createCanvas(50, 50)
 * const ctx = canvas.getContext('2d')
 * @example
 * // Node.js + Fabric.js
 * import { StaticCanvas } from 'fabric/node'
 * const ctx = new StaticCanvas(null, { width: 50, height: 50 }).getContext()
 * @example
 * // Browser + Native Canvas
 * const canvas = document.createElement('canvas')
 * canvas.width = 50
 * canvas.height = 50
 * const ctx = canvas.getContext('2d')
 * @example
 * // Browser + Fabric.js
 * import { Canvas } from 'fabric'
 * const ctx = new Canvas('canvas', { width: 50, height: 50 }).getContext()
