What it tells the agent

The instruction file, verbatim from the audited commit — this is the text the model reads, and the surface the audit's instruction layer examines. Quoted here so you can judge it without cloning anything.

【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。
   - 性能允许时启用, `prefers-reduced-motion` 时降回静态截图。
3. **WebGL fragment shader** (高阶, 慎用):
   - 用 jsdelivr CDN 引 `regl` 或 inline plain WebGL。
   - shader 写 domain-warp noise; 单个 quad, 一个 uniform `u_time`。

【顶层文字层】
- 居中或左下: 一句巨型金句 (5-7vw, 衬线或粗 sans), 字体: `Source Serif Pro` / `Inter Tight` / `Manrope Black`。
- 文字色用 paper white `#fafaf8` 或 ink, 取决于背景明暗; 加 `mix-blend-mode: difference` 让它在任何流体颜色上都可读。
- 副标 (小 sans, opacity 0.7) 一行。
- 底部可选 CTA chip 或 hairline + 元数据 row。

【调色 — 4 选 1, 不要彩虹】
- 🌅 **Solar Peach** — `#ffb18a` + `#f78b4c` + `#d97757`, 暖橙桃。
- 🌊 **Ocean Aqua** — `#5ac8fa` + `#0a84ff` + `#1e3a8a`, 海蓝。
- 🌌 **Aurora Violet** — `#a78bfa` + `#7c5cff` + `#1e1b4b`, 极光紫。
- 🌿 **Forest Mint** — `#86efac` + `#34d399` + `#065f46`, 苔森林。

【设计细节】
- 严禁: 多色彩虹 (>4 个色相)、PowerPoint 渐变、霓虹荧光叠加。
- 字体: 中文用 `Noto Serif SC` (display) / `Noto Sans SC` (副标)。
- 严禁外链图片; 全部 CSS + SVG + 可选 canvas。
- 必须用用户提供的金句 / 标题; 如果用户输入是数据 → 提炼一句 ≤ 18 字的金句。
- 单文件 HTML, 可被 `prefers-reduced-motion` 关动效。
