Gitea's inline script carries `appUrl: 'https:\/\/gitea.example.com\/'`, and
rewriteAbsolute only matched the literal `https://` form. So appUrl survived
pointing at the real host while every visible link was rewritten correctly.
The failure was quiet rather than obvious: the page rendered, and only the URLs
Gitea's JS BUILDS from appUrl went wrong — cross-origin to the real host,
answered with its login HTML. The heatmap reported "Unexpected token '<'" while
parsing JSON, and the event worker failed the same way.
Third instance of the same class today, after the asset paths and appSubUrl: a
URL hiding in a shape the rewriter did not think to look for. All three were
found by loading the page, none by the tests — and all three now have a test
written against a live sample rather than an imagined one.
