// A single shared libauth for the whole page.
//
// WHY THIS FILE EXISTS
// libauth initialises its WASM crypto (secp256k1, sha256, ripemd160, …) with a
// TOP-LEVEL AWAIT. If two bundles each carry their own copy, each has its own
// unsettled init, and esbuild's inlined dynamic imports can hand out a bundle's
// exports before that init completes. Symptom, observed on cold load:
//
//   TypeError: Cannot read properties of undefined
//              (reading 'derivePublicKeyCompressed')
//     at deriveNostrPublicKey (wizardconnect.js)
//     at generateKeyExchangeCredentials
//     at initiateDappRelay
//
// — failing 65 ms in, then "working" on every retry once the WASM had warmed.
// A bug that disappears when you look at it twice is exactly the kind that
// ships.
//
// So libauth becomes a real, separate ES module that every other bundle imports
// by bare specifier, resolved through the import map in register.html. The
// browser's module loader guarantees a dependency's top-level await settles
// before any importer evaluates — the ordering we need — and the page downloads
// libauth once instead of three times.
//
// WHY THE EXPORTS ARE LISTED BY HAND
// `export *` would defeat tree-shaking and ship all ~1 MB of libauth. This list
// is the union of what our own modules use and what @wizardconnect/core and
// /dapp import (they resolve to this module too, via the import map). Missing a
// name would be a runtime failure in a path we cannot unit-test, so
// build-web.mjs verifies this list against the imports every other bundle
// actually emits, and fails the build if anything is absent. Add freely; the
// check will tell you if you remove something still in use.
