xiety/AnkiPoetry — reverse-engineered prompt

Build me a simple web tool that turns a poem or play text into Anki import files for memorizing it.

I want to paste text in a special format where # is the book title, ## is the chapter or scene title, and @ marks lines that should be shown but not memorized. The app should let me set a deck name, chunk size, word wrap, colors, overlap between chapters, line numbers, continuous numbering, dots around wrapped text, and whether to add title preview cards.

The output should be three CSV files for Anki, organized for word, line, and page memorization. The generated cards should show previous lines for context, repeat the last line at the top of the next page, optionally color lines, and make the pages fit nicely on a phone screen. Keep the interface clean and usable in the browser. Include enough sample text so I can test it right away.
