Type Alias ResolveTypeString<S, R>

ResolveTypeString: S extends `${infer A}|${infer B}`
    ? ResolveTypeString<Trim<A>, R>
    | ResolveTypeString<Trim<B>, R>
    : Trim<S> extends keyof TypeMap
        ? TypeMap[Trim<S>]
        : Trim<S> extends keyof R ? R[Trim<S>] : unknown

Resolves a single type-name string (possibly a a|b|c union) to its runtime TypeScript type. Falls back to unknown for unknown aliases.
