963 markdown files reformatted with the repository's pinned prettier so pnpm format:check covers the folded tree like every other repo file. The formatter's embedded-language pass also normalized code fences (TS semicolons, closed HTML tags in examples, lowercased CSS hex colors, one renumbered list that skipped an index). Alphanumeric token deltas vs the fold commit were audited file-by-file; all are formatter-equivalent markup normalizations plus the four sanitized skills.

Promise.all() for Independent Operations
When async operations have no interdependencies, execute them concurrently using Promise.all().
Incorrect (sequential execution, 3 round trips):
const user = await fetchUser();
const posts = await fetchPosts();
const comments = await fetchComments();
Correct (parallel execution, 1 round trip):
const [user, posts, comments] = await Promise.all([fetchUser(), fetchPosts(), fetchComments()]);
