Enhance Web with 3D & Cinematic Motion

Degree of freedom: MIXED. Fit and stack choice [HIGH freedom]; budget, fallbacks, SSR, and verify [LOW freedom — run exactly].

Add Three.js / React Three Fiber scenes, GSAP scroll choreography, and physics motion to an existing web project — without rewriting it, breaking the build, blowing the performance budget, or shipping a blank canvas to users on weak devices or with WebGL disabled.

This is not a "drop a spinning cube on the homepage" skill. It audits the repo first, decides whether 3D actually serves the page, picks the smallest library combination that fits the existing stack, and ships the effect with fallbacks and reduced-motion support from the first commit.
