description	Compact a lesson by folding answered ?> Q&A pairs into <details> blocks, so a re-read flows past them. Run after the user has worked through a lesson.

studyground: recap

Fold the consumed Q&A in a lesson into collapsed <details> blocks. Leave the main narrative intact.

Steps

1. Read lessons/<slug>.md.

2. For each pair of ?> question followed by <!-- answer:start --> ... <!-- answer:end -->, replace both the question line AND the answer block with:

   <details>
   <summary>?> {question text}</summary>
   
   {original answer body, verbatim}
   
   </details>
   

3. Leave ?>> btw markers (they're already folded), :::exercise blocks, and <!-- feedback:start --> ... <!-- feedback:end --> blocks untouched.

4. Do not touch <!-- answer:pending --> markers (those haven't been asked yet — keep them visible so the user knows there's a question pending).

5. Save the file.

Constraints

• Preserve the question text verbatim.
• Preserve the answer body verbatim (don't summarize or shorten).
• Don't add anything else (no "Q&A archive", no extra headings).
• Don't update progress.json.

Why this exists

After 4–5 ?> markers in one lesson have been asked and answered inline, the file gets long and the main narrative is harder to skim on a second read. Folding collapses the Q&A behind a single line, but keeps it one click away.

Note: in the reader, an answered ?> is open by default (so the learner sees the answer they earned). Recap is the explicit "I've already absorbed this, now hide it on re-read" action — it overrides the default by rewriting the source into a raw <details> block.
