# One frontend build serves four sites: tala.run for the language,
# talac.tala.run for the compiler, talafmt.tala.run for the formatter and
# talalint.tala.run for the linter. The page picks its content from the host
# name. xsharp-lang.xyz, the former domain, answers with a permanent redirect to
# the same path on tala.run. tazel.tala.run, where the build system was
# documented, answers with a permanent redirect to tazel.net, its own site.
# The policies allow Cloudflare Web Analytics, which Cloudflare adds to each page.
