199-200: Consider sanitizing hash input for selector queries.
window.location.hashis user-controllable and directly interpolated into CSS selectors. While invalid selectors will throw aDOMException(causing silent failure here), malicious payloads could potentially craft selectors that match unintended elements.For a standalone demo this is low risk, but in production code, validate that the hash matches expected tab IDs.
🛡️ Proposed defensive fix
changeTab(hash) { if (!hash) { return; } + // Validate hash matches expected pattern + if (!/^#tab-\d+$/.test(hash)) { + return; + } + const anchor = document.querySelector(`.transformer-tabs a[href="${hash}"]`); const panel = document.querySelector(hash);🤖 Prompt for AI Agents

This prevents DOMExceptions from invalid selectors and avoids matching unintended elements by sanitizing or whitelisting the hash first.

"#tab-2", and "#tab-3"; fix by either adding a corresponding navigation link
(e.g., add an <li><a href="#tab-4">…</a></li> alongside the existing tab
anchors) so users can access the panel, or remove the `#tab-4` panel entirely if
it’s not needed; ensure the added anchor matches the panel id and follows the
same active/ARIA conventions used by the other tab anchors (e.g., same class
usage and ordering).

Stray code fence causes markdown lint warning.
Line 111 contains an orphan triple-backtick that isn't opening or properly closing a code block. This triggers MD040 (fenced code blocks should have a language specified).
Review the intended structure—this fence appears misplaced and should likely be removed or properly paired with a preceding opening fence.

Orphan panel: #tab-4 has no navigation link.
The navigation contains links for #tab-1, #tab-2, and #tab-3, but #tab-4 exists as a panel (lines 158-161) without a corresponding tab link. Users cannot reach this panel through the UI.
Either add a tab link for #tab-4 or remove the orphan panel.
