Why it matters

Mathematical centering doesn't always look centered to the human eye. Icons with more visual weight on one side may need to be shifted slightly to appear balanced. Trust your eye over the numbers, but limit adjustments to 1-2px.

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.
