Usar `check_same_thread=False` permite a FastAPI usar la misma base de datos SQLite en diferentes hilos. Esto es necesario ya que **una sola request** podría usar **más de un hilo** (por ejemplo, en dependencias).

     * Another way to express this signature would be to bound <V> by @NonNull and accept
     * LF<? extends @Nullable V>. That might be better: There's currently no difference between the
     * outputs users get when calling this with <Foo> and calling it with <@Nullable Foo>. The only
     * difference is that calling it with <Foo> won't work when an input Future has a @Nullable
     * type. So why even make that error possible by giving callers the choice?

     * mix of "less than" and "greater than"). We've also switched to "strictly less than" rather
     * than "less than or equal to" because of *handwave* the difference between "endpoints of
     * inclusive ranges" and "Cuts."
