/**
 * Represents a deeply branded type.
 *
 * Recursively walk a type and replace it with a branded type related to the
 * original. This is useful for equality-checking stricter than
 * `A extends B ? B extends A ? true : false : false`, because it detects the
 * difference between a few edge-case types that vanilla TypeScript
 * doesn't by default:
 * - `any` vs `unknown`
 * - `{ readonly a: string }` vs `{ a: string }`
 * - `{ a?: string }` vs `{ a: string | undefined }`
 *
 * __Note__: not very performant for complex types - this should only be used
 * when you know you need it. If doing an equality check, it's almost always
 * better to use {@linkcode StrictEqualUsingTSInternalIdenticalToOperator}.
