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.

Hoist Static JSX Elements
Extract static JSX outside components to avoid re-creation.
Incorrect (recreates element every render):
function LoadingSkeleton() {
return <div className="animate-pulse h-20 bg-gray-200" />;
}
function Container() {
return <div>{loading && <LoadingSkeleton />}</div>;
}
Correct (reuses same element):
const loadingSkeleton = <div className="animate-pulse h-20 bg-gray-200" />;
function Container() {
return <div>{loading && loadingSkeleton}</div>;
}
This is especially helpful for large and static SVG nodes, which can be expensive to recreate on every render.
Note: If your project has React Compiler enabled, the compiler automatically hoists static JSX elements and optimizes component re-renders, making manual hoisting unnecessary.
