I let an AI write 6 WebGL hero sections — here's the one-CSS-variable reskin trick, and the honest review count

A developer built six AI-generated WebGL hero sections and then spent multiple review passes fixing browser, accessibility, motion, and size issues to make them shippable.

The piece argues that AI-first UI code still needs careful human review, especially for polished visual experiences and production constraints.

It also shows a practical theming trick: WebGL scenes can read colors from CSS custom properties, so updating one design token can reskin the whole effect.

Using MutationObserver and related CSS-driven patterns, the visuals can stay in sync with brand tokens without editing shader code.
