How To Use
The top pane is always the plain text. The lower pane is always the encoded Base64 value. Edit either one and the other updates immediately.
Standard keeps `+`, `/`, and `=` padding. URL-safe swaps those characters for `-` and `_` and removes trailing padding.
The Wrap toggle only changes how long encoded output is displayed in the editor. It does not change the actual value.
