In commit 600c8a78484c93030f79a4fa4a8bc8ca603296f1, we have introduced an unintentionally breaking change to how redirects are handled, thus breaking every single-page application deployed to a non-index project. This cannot be easily fixed due to Codeberg Pages already having a mix of broken and fixed redirects in manifests without any way to tell them apart, but we can at least emit a diagnostic for redirects that are statically known to be broken at deploy time. See also #273.
