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.

CSS content-visibility for Long Lists
Apply content-visibility: auto to defer off-screen rendering.
CSS:
.message-item {
content-visibility: auto;
contain-intrinsic-size: 0 80px;
}
Example:
function MessageList({ messages }: { messages: Message[] }) {
return (
<div className="overflow-y-auto h-screen">
{messages.map((msg) => (
<div key={msg.id} className="message-item">
<Avatar user={msg.author} />
<div>{msg.content}</div>
</div>
))}
</div>
);
}
For 1000 messages, browser skips layout/paint for ~990 off-screen items (10× faster initial render).
