I recorded a 41-minute tutorial on how I use Astra to create insane three.js websites in Codex. I've been using DiffUI to brainstorm UIs before moving into code. It's fast and cheap, generates multiple variants and lets me branch ideas, sections, logos, and other components. Then I use "Copy for agent" and bring everything into Codex where I add transparent PNG layers, animations, and three.js skills.
