コントラクト

• Base64.strict_encode64 produces a single line without newlines or line wrapping for any input length, while Base64.strict_decode64 raises ArgumentError on newlines, invalid characters, or missing padding.
• Base64.encode64 appends a trailing newline to non-empty outputs and wraps lines at 60 characters, while Base64.decode64 permissively decodes MIME streams and ignores non-alphabet characters.
• Base64.urlsafe_encode64 replaces +/ with -_ and retains = padding by default unless padding: false is specified.
• Base64.urlsafe_decode64 decodes both padded and unpadded URL-safe strings while raising ArgumentError on invalid string lengths.
• Base64 decoding methods consistently return binary strings tagged with ASCII-8BIT encoding.
