			ORDER IS THE POINT, and this comment sits below the redirect rather than
			above it for the same reason. Those four lines are the whole critical
			path and they are the first ~180 bytes of the document:

			  charset     first, so the parser never has to restart. It has to appear
			              within the first 1024 bytes; an earlier draft of this file
			              opened with this very comment and pushed it past that.
			  preconnect  starts DNS, TCP and TLS to lab271.io *before* the navigation
			              is requested, so the handshake overlaps the rest of this
			              parse instead of queueing behind it. On a cold connection
			              this is the only change here that saves real time.
			  script      an inline classic script, so it runs synchronously the
			              instant the parser reaches it. replace() rather than
			              assignment, so this page leaves no history entry and Back
			              does not bounce the visitor straight back into it.
			  refresh     the same redirect for anyone without JavaScript. Zero delay,
			              which search engines treat as a permanent redirect.

			Everything below is for crawlers and for the rare visitor who actually
			sees this page. None of it can start the navigation any sooner, and every
			byte of it placed higher would delay the navigation for everyone.

			GitHub Pages cannot return a 301. A real one needs a custom domain on this
			repository, and lab271.io resolves to CloudFront rather than to Pages, so
			it cannot be one. The four lines above are the strongest redirect a static
			host can give.

			Deliberately no `noindex`: it contradicts the canonical, and would ask
			search engines to drop this page rather than consolidate it onto the new
			one.
