tessl review fix ./skills/frame-liquid-bg-hero/SKILL.md【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】
radial-gradient(...), 颜色取自调色板。@keyframes 平移 + scale + hue-rotate, 周期 8-14s, 错峰; 整个画面叠 mix-blend-mode: screen 或 overlay。backdrop-filter: blur(80px) 让边缘更糊。requestAnimationFrame 画 metaballs 或 simplex noise field。prefers-reduced-motion 时降回静态截图。regl 或 inline plain WebGL。u_time。【顶层文字层】
Source Serif Pro / Inter Tight / Manrope Black。#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。【调色 — 4 选 1, 不要彩虹】
#ffb18a + #f78b4c + #d97757, 暖橙桃。#5ac8fa + #0a84ff + #1e3a8a, 海蓝。#a78bfa + #7c5cff + #1e1b4b, 极光紫。#86efac + #34d399 + #065f46, 苔森林。【设计细节】
Noto Serif SC (display) / Noto Sans SC (副标)。prefers-reduced-motion 关动效。f2760fd
