Pull request overview

Removes the temporary IPC 2026 navigation entry so the IPC page is no longer linked from the site header, while also introducing a backup copy of the IPC page content and adjusting tag rendering in the archive listing.

Changes:

• Removed the time-gated “IPC 2026” header navigation link.
• Added an ipc26.astro.bak backup page containing IPC 2026 content.
• Modified archive tag rendering logic to include a "None" fallback (currently ineffective).

src/components/ArchiveListing.tsx	Changes tag rendering expression to add a fallback string (but the fallback won’t actually render as written).

item.tags?.map(...) || "None" will never render "None": map always returns an array (truthy), and this branch only runs when item.tags.length > 0. If you want a fallback, render it when tags are missing/empty (e.g., move the fallback to the false branch) rather than using || here.

	{item.tags?.map((e, idx) => <p key={idx} className="p-1 bg-slate-600 rounded-md">{e}</p>) || "None"}
	</div> : <></>}
	{item.tags.map((e, idx) => <p key={idx} className="p-1 bg-slate-600 rounded-md">{e}</p>)}
	</div> :
	<div className="flex flex-row gap-x-2 flex-wrap">
	<p>Tags:</p>
	<p className="p-1 bg-slate-600 rounded-md">None</p>
