Best approach

A true all-in-one calculator would need every manufacturer’s model/lens database, which is usually not public and changes often. This launcher keeps the data official by sending you directly to the current tools.

Tip: put this file on your desktop, NAS, or website. It does not need a backend. Cards marked “open only” have preview disabled because those sites are likely to block iframe embedding.
