Walkthrough

Added "probelab.io" to the excluded domain list in the lychee.toml configuration file with an inline comment indicating bot protection/403 errors. This prevents link checking from targeting this domain.

Check name	Status	Explanation	Resolution
Title check	❓ Inconclusive	The title 'fix: probelab link checks' is related to the changeset but overly broad and vague. It refers to 'link checks' without specifying that the fix involves excluding a domain from link checking due to bot protection.	Consider a more specific title such as 'fix: exclude probelab.io from link checks' to better convey the actual change of adding a domain to the exclusion list.
