Replace the Tailwind CDN page with a static stylesheet. Make the
generator emit the new markup and fill the Brewfile block from the
casks. Map cask names to repository names for projects whose names
differ.
GoReleaser regenerates each cask with a postflight block, which Homebrew rejects. A script now rewrites it to postflight_steps before test-bot runs. The four current casks are rewritten as well.
