Using this tool
Generate alternating upper- and lowercase letters without breaking grapheme sequences.
Example: `alternating case` becomes `aLtErNaTiNg CaSe` with the default starting case.
The pattern advances over cased letters, so punctuation, digits, and emoji do not add unexpected alternations.
This is a display transformation; it does not identify or preserve intentional acronyms.
