Real aerospace formulas embedded in Claude skills, but AI domain expertise packs already exist.
Three.js orbital mechanics beats legacy suites, but core math (Hohmann) is 50 years old.
First API solving the actual orbital compute placement problem with SGP4 physics, not simulation.
Clean 3D quantum viz, but PhET simulations already cover this ground without AI.
Educational Mars sim, but page content doesn't match the project title.
Playwright-driven crawling + deterministic token extraction plus an LLM for semantic labeling is a clever pipeline — it doesn’t just scrape CSS, it produces an AI-optimized .design-memory folder with tokens, component recipes, and multi-page merge/diff capabilities. Expect variable fidelity on highly dynamic or framework-heavy sites since the approach depends on selector heuristics and an API key, but the CLI commands (learn, install, diff) and docs show this is more than a research sketch.
