This URL redirects to https://code.mendhak.com/eleventy-satisfactory/.

The same URL in a different form — a trailing slash — so both are treated as one site rather than two: one history, measured once. Lighthouse follows the redirect, so the numbers below describe the page actually served; the only cost is an extra hop on each run.

Lab data is measured using Lighthouse, Mobile mode unless otherwise specified. Field data is reported from Chrome UX Report (using p75 measurements).

LCP LAB Simulated vs LCP FIELD

Lab 1.70 s
Field p75 831 ms

The lab LCP is 2.05× the field p75 — real users likely have above-average hardware or network connectivity.

0% of pixels differ — they are identical. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.
