This directory contains code for matching URLs against a set of routes.
The code here is responsible for parsing a set of routing rules defined in a JSON format, storing them, and matching them against URLs.
Active routes can be matched against an @route CSS rule, allowing different styles to be applied based on the current route(s).
The active routes will be exposed through the navigator.routes JavaScript API (exact naming TBD).
