Shifts each letter forward through its own alphabet by a fixed amount and wraps around at the end — a classic teaching cipher and puzzle-solving tool, not real cryptography. Handles Latin and Cyrillic (Bulgarian) letters in the same pass, case-preserving; digits and punctuation pass through unchanged. Type on either side and the other updates live. Runs entirely in your browser.
