/**
 * did:web Resolver
 *
 * Resolves did:web DIDs to DID Documents by fetching the well-known document
 * over HTTPS, per the did:web method spec.
 *
 * URL mapping (did:web method spec §3.2):
 *   did:web:example.com         → https://example.com/.well-known/did.json
 *   did:web:example.com:a:b     → https://example.com/a/b/did.json
 *   did:web:example.com%3A3000  → https://example.com:3000/.well-known/did.json
 *
 * Percent-encoded characters in each colon-separated segment are decoded
 * (notably `%3A` for a host:port colon).
 *
 * The fetch implementation is pluggable so callers — and tests — can supply
 * their own transport; it defaults to the global `fetch`. The resolver never
 * throws: a non-did:web input, non-OK response, malformed document, or
 * transport error all resolve to `null`.
 *
 * Mirrors the shape of {@link createDidKeyResolver}.
 *
 * @see https://w3c-ccg.github.io/did-method-web/
