🟢generate_handwriting_sheet(text, line_size, paper, orientation, title, ...)

Use this when the user wants handwriting worksheets, tracing worksheets, letter tracing or handwriting practice sheets as a printable vector PDF. Supports up to 600 characters and word wrapping. Repeats text to fill each tracing row when repetitions are omitted, or uses an explicit one to four copies, followed by a blank copy row. Does not support cursive. Print letters only. Latin, Greek and Cyrillic supported. Oversized words produce a clear error.
