Thanks for the PR — a few small fixes please to avoid rendering/Sandpack breakage:

Please revert wrapping MDX components in backticks with {=html}. Examples: , , , , , , , . They should remain real MDX components.
Fix the mangled code fences (e.g. processQueue): keep the fence metadata on its own line and the code underneath (don’t put the fence and code on the same line).
Remove the stray backslash before the heading (change ### What happens... to ### What happens...).
Don’t wrap and similar components inside code fences — render them as components or use the repo’s admonition pattern.
Prefer pipe-style Markdown tables over preformatted text, and run the repo formatter (prettier/markdownlint) to normalize line-wrapping and list indentation.
After making these changes, please run the local/CI site preview to verify Sandpack examples and MDX components render correctly.
Thanks — happy to re-review once those are addressed.

Thanks for the detailed feedback!

I’ve fixed the MDX component rendering, corrected the Sandpack code fences, removed the stray backslash in the heading, converted the tables to pipe-style Markdown, and verified the page renders correctly.

Could you please take another look when convenient? Thanks again!
