The configuration is proved, not promised.
Three scripts ship with the theme and run 169 checks between them: one edits every config value, rebuilds and inspects the output; one drives Chromium with every provider endpoint intercepted, so no request ever leaves; one sweeps each route for a single h1, a working menu at every width and a clean console. You re-run them after your own changes, which is the difference between a claim and a receipt.
