【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。

pptx-html-fidelity-audit

nexu-io/open-design

Audit a python-pptx export against its source HTML deck, identify layout/content drift (footer overflow, cropped content, missing italic/em, lost styling, off-rhythm spacing), and re-export with strict footer-rail + cursor-flow layout discipline. Use this skill whenever the user has a .pptx that was generated from an HTML slide deck and asks to compare/audit/verify/fix the export — including phrases like "compare ppt with html", "fidelity audit", "fix the pptx", "ppt is cut off", "footer overlap", "italic missing in pptx", "re-export the deck", "pptx-html-fidelity-audit", or any case where a python-pptx → HTML round-trip needs verification or repair. Also trigger when the user shows you a deck.html and a deck.pptx side by side and is debugging visual differences.

hatch-pet

nexu-io/open-design

Create, repair, validate, preview, and package Codex-compatible animated pet spritesheets from character art, screenshots, generated images, or visual references. Use when a user wants to hatch a Codex pet, create a custom animated pet, or build a built-in pet asset with an 8x9 atlas, transparent unused cells, row-by-row animation prompts, QA contact sheets, preview videos, and pet.json packaging. This skill composes the installed $imagegen system skill for visual generation and uses bundled scripts for deterministic spritesheet assembly.
