+  "log out" or "sign up", inflections included — a second spelling for one button reads as a second
+  thing; the noun ("a sign-in error", "the sign-in identifier") is unaffected. Guarded over the
+  shipped core catalog by `src/i18n/load.test.ts` (a test file cannot live in `locales/`, which loads

 - Use well formed, standard compliant, rich URIs. Prefer state in the URL over POST:ing in for
   for example list pages with filters and pagination. Do: "ids=x&ids=y" and not "ids[]=x&ids[]=y"
   and not "ids=x,y".
