Turn A Dense Textbook Chapter Into Flashcards

You have got a chapter highlighted in six colours and no actual memory of what it said. This takes the text you paste in and turns it into question and answer flashcards, grouped by topic, ready to drill. Good for anyone revising from a textbook, a set of lecture notes, or a long article.

<task>
**Generate** a set of flashcards from the pasted text.
1. Identify the 12 to 20 most testable facts, definitions, or relationships in the material.
2. Write each as a question on one side and a short answer on the other.
3. Avoid yes/no questions. Favour questions that require recalling a specific term, number, sequence, or cause and effect.
4. Group the cards under the subheadings that already exist in the text, or create your own if none exist.
</task>

<output_format>
A numbered list of cards under grouped headings. Each card shown as "Q:" then "A:" on the next line. Keep answers under 20 words each. End with a one-line count of total cards produced.
