The Download buttons pointed at TheseusNavigator-Setup-0.3.44.exe, which the
ship process had long since archived off dl.silentmode.st — a 404 for anyone
arriving from theseus.x. Buttons now use dl.silentmode.st/latest/<name>,
which the download host redirects to the current versioned file, so the page
cannot go stale again. Versions and hashes are refreshed from the releases
manifest at load (the baked-in 0.3.48 / 0.18 values are the fallback), and
theseus.x/dl is a memorable landing that carries only the stable links.
