NEVER: Dynamically construct class names (`bg-${color}-500`); use object lookup with complete strings

Write complete class names for Tailwind to detect them

Why it matters

Tailwind's build process scans your source files for complete class name strings. It cannot execute JavaScript or interpolate template literals. Dynamically constructed classes like bg-${color}-500 will be purged from production builds.

Built by Gleb Stroganov, design engineer at Evil Martians.

The rules come from other people's skills and guidelines — Vercel, Rauno Freiberg, @Ibelick, impeccable, Emil Kowalski, Tailwind, RAMS — each one credited on the Sources page. The work here is extraction and wiring: every rule is pulled into one corpus, given a good and a bad example you can operate, a MUST/SHOULD/NEVER rule an agent can paste, and a link back to where it came from.
