Color filters

Add the "Color filters" animated icon (id: color-filters) from Generative Icons by LottieFiles to this project.

1. Look at the project first: framework, package manager, and where static assets are served. In a monorepo, target the app that needs the icon.
2. Install the runtime: `npm install @lottiefiles/generative-icons-runtime`. For React or Next.js, also install `@lottiefiles/generative-icons-react`. Use the project's package manager.
3. Run `npx generative-icons init`, then `npx generative-icons add color-filters`. Follow the agent skill that init writes to `.agents/skills/generative-icons/` (and `.claude/skills/generative-icons/`). Commit `generative-icons.json`, the copied files and `.generative-icons/lock.json`.
4. Render the icon with these settings: color #ffffff, style outline, weight 2, motion light, theme dark. In React, use `<AnimatedIcon icon={icon} src={src} size={24} color="#ffffff" variant="outline" weight={2} motion="light" theme="dark" />` inside a `'use client'` component. Otherwise use `createIcon(canvas, { icon, src, ... })` from `@lottiefiles/generative-icons-runtime` and call `destroy()` when the element is removed.
5. Play it on the interaction it belongs to (click, hover or confirmation). The icon is decorative, so the parent control needs an accessible label. Reduced motion is handled by the runtime.
6. If this is a native iOS or Android app instead, download https://generativeicons.com/assets/color-filters.lottie and play it with the dotLottie player for that platform.
