Adding a new site is a one-object change to
src/sites.ts. SeeAdding a site below.
- A pill-shaped ▾ Fold button appears in each code block's header,
next to Copy / Download. - Clicking it hides the code body and replaces it with a dimmed
▸ Click to unfold line. - Clicking that line — or the button again — expands the block.
- On Qwen, expanding dispatches a
resizeevent so the Monaco editor
redraws its virtual viewport correctly.
