Contains `wait-predicate`, a generic polling function that repeatedly evaluates a predicate until it returns truthy or a deadline expires. Uses deadline-based timing (not interval counting) so slow predicate evaluations don't extend the total timeout. Configurable interval and timeout. This is a clean, reusable pattern for any polling scenario (e.g., waiting for async operations, file system changes, network responses) and can be extracted with minimal modification.

Implements a Clojure map-to-XPath DSL. Users write queries like `{:tag :a :fn/text "Press Me"}` and get `.//a[text()="Press Me"]`. Supports attributes, text, position, CSS-like combinators, and logical operators. The conversion is purely functional and stateless, making it easy to extract and reuse in any project that needs to generate XPath expressions programmatically.

Overrides `clojure.test/testing` macro via `alter-var-root` to inject platform/context information (e.g., browser, driver type) into test output. This is a non-obvious pattern for enhancing test reports without modifying test code. The approach is reusable for any project that wants to add custom metadata to test results, though it requires careful handling of macro internals.
