Shipped a small dev tool: an LNURL debugger. Paste a Lightning address or lnurl1... string, it resolves + fetches + validates the response against LUD-06/LUD-04, and has a signing sandbox that reproduces a real bug I hit earlier this week (noble-curves v1 vs v2 default to different signature semantics for the same key+message — silent, confusing failure if you don't know to check). Client-side only, one file, view-source-able.
