// R-553 — the deploy path's refusals carry a KIND, so the API can pick its status code without
// reading the customer's Hungarian sentence. The sentences themselves are unchanged (a test pins
// each one byte-for-byte); `internal/util.KindErrorf` builds the message exactly as fmt.Errorf did.
//
// Before this, internal/api/router.go matched „kötelező", „memória", "does not exist" and
// "already deployed" in the error text — so localisation slice 2 would have turned every validation
// refusal into a 500.

	// running. Refused, because a `compose down` or a second `compose up -d` in the middle of the
	// deploy's own `up` makes BOTH fail, and the deploy then records „not deployed" over whatever
	// containers the race left behind. Pinned by TestR634_StopAndStartRefuseADeployingStack.

// it used to be rendered here in Hungarian, so an English page showed a Hungarian line). Pinned by
// TestR575_OvercommitWarningFollowsTheLanguage.
