Decision brief

What it does—and where it fits

WebGL-style fluid displacement background with a quote overlay, suited to video intros, landing heroes, or posters.

Best for

    Not for

    • Tasks that require unconfirmed production actions or broad system permissions.
    • Environments where the pinned source and install steps cannot be inspected.

    Installation

    Inspect first. Install second.

    The source command is displayed only when detected. A safe inspection prompt is always available so your agent can explain every action before execution.

    Safe inspection promptEditorial

    Inspect the Agent Skill "frame-liquid-bg-hero" from https://github.com/nexu-io/open-design/blob/89d6d4ef21baf80f871595abdf6f7de6e941dd44/skills/frame-liquid-bg-hero/SKILL.md at commit 89d6d4ef21baf80f871595abdf6f7de6e941dd44. List every install step, command, network request, credential, file read/write, external action, and rollback step. Explain whether it fits my task. Do not install or execute anything until I approve.

    Workflow

    What the source asks the agent to do

    The source does not provide enough structured workflow evidence for a step-by-step guide.

    Permission review

    Static risk signals and limitations

    No configured static risk pattern was detected

    This is not proof of safety. Runtime behavior, indirect dependencies, and hidden external systems are outside the static scan.

    【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: screenoverlay
      • 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。
