【模板: 流体背景 Hero】 【意图】可作为视频片头帧、SaaS landing 顶部 hero、海报底图。WebGL 流体感, 但用 CSS / canvas 退化绘制, 确保单文件可双击打开。Inspired by hyperframes vfx-liquid-background。

【画布】1920×1080 (横) 或 1080×1920 (竖), 二选一。背景占满。

【流体背景 — 3 种实现, 按用户偏好选】

  1. CSS 多层 radial-gradient 错位呼吸 (最稳, 默认推荐):
    • 3-5 个大椭圆 radial-gradient(...), 颜色取自调色板。
    • 每个椭圆套 @keyframes 平移 + scale + hue-rotate, 周期 8-14s, 错峰; 整个画面叠 mix-blend-mode: screen 或 overlay。
    • 顶层加 1 层 backdrop-filter: blur(80px) 让边缘更糊。
  2. Canvas + simple perlin noise (中阶):
    • 80 行 inline JS, 用 requestAnimationFrame 画 metaballs 或 simplex noise field。
