Explain Code

Explain the user-scoped code as a short, scannable post. Prefer plain-English prose and small code sketches over exhaustive walkthroughs.

Defaults

Match the user's scope exactly.
Use this structure: # title, ## TL;DR, then one or more ## sections.
Each ## section covers one idea and includes at least one fenced code block.
Keep prose simple and snippets small.
Simplify code when useful, but stay faithful to behavior.
Do not invent intent that the code or prompt does not support.
When design-taste-frontend or gpt-taste is also in scope for UI or markup output, follow their stricter presentation rules (no emojis in code, markup, text content, or alt text) even though this skill otherwise allows plain headings.

One plain-English line naming the topic.
