Encoder / Decoder
Transform browser-local text and evidence across common encodings with strict decode validation, format detection, copy variants, history, and shareable state.

Encoding Notes
- Base64URL uses URL-safe characters and often omits padding in token segments.
- Hex and binary decode require complete byte groups so malformed evidence fails clearly instead of producing replacement characters.
- UTF-16LE Base64 is included for reviewing encoded command text while keeping all transforms local to the browser.
