22-22: LGTM! Clean fix that resolves the broken link.

The removal of the trailing slash from the ESPresense Companion link (line 22) correctly addresses the 404 issue and aligns with the pattern used by all other relative links in the file (./nodes, ./devices, ./sensors, ./troubleshooting, ./credits). The addition of a proper trailing newline (line 45) follows Unix file conventions. Both changes are straightforward and appropriate.

Also applies to: 45-45
