Paper Shaders for video

Paper Shaders draws designer-tuned WebGL shaders into a canvas. Left alone it animates from the wall clock, which flickers and drifts in a video render. This skill mounts every shader at speed 0 and draws each frame from the timeline, so the same frame always gives the same picture.

Gates

1. Pin @paper-design/shaders@0.0.82. Use that exact version everywhere. Never use 0.0.47–0.0.76: they are PolyForm Shield, not open source. Bumping the version follows references/licensing.md.
2. Speed 0, time from the timeline. Mount shaders only through templates/paper-preset.js. Never set speed above 0, and never let scene code read Date.now(), performance.now(), requestAnimationFrame or unseeded Math.random().
3. No credits here. Shader layers render locally for free. If the video also needs generated footage, voice or music, that is the varg-ai skill: call estimate_cost and wait for the user's approval before any generation.
4. Rights. Logos and stills fed to image presets must be the user's own or licensed. Do not apply a shader to another company's logo.
5. Stills, not footage. Paper's image filters take images only. Grade and add grain to footage with HyperFrames media treatments instead.

Workflow

A person approves at each checkpoint (looks, stills, motion) before the next step. Commands run from the skill folder; HF stands for the pinned CLI, npx --yes hyperframes@0.8.206.
