RFC 3986 URL Compliance
Characters like spaces, question marks, ampersands, and slashes must be percent-encoded to prevent breaking HTTP routing or query parsing.
Architecture & Privacy
- Dual RFC 3986 encoding modes: Component (encodeURIComponent) and Full URI (encodeURI).
- Safe decoding recovery: Unescaped lone "%" characters are automatically escaped to prevent URIError crashes.
- Deep Query Param extraction: Parses nested URL search params into individual key-value records.
