// Package-level signup-visibility hook, wired once at startup the same way
// middleware.SetDefaultPasswordSettings wires the password policy: a shared
// component (SidebarSignIn's "Create an account" link) renders inside many
// page templates whose call sites have no per-page flag, so the templates
// package asks a closure backed by the live settings registry instead.
// The closure is re-evaluated on every render, so admin changes apply
// immediately without a restart.

// signupVisible reports whether public signup surfaces (front page, login
// page, logged-out sidebar) should render. Unwired → default true.
var signupVisible func() bool

// SetSignupVisibility wires the live visibility closure from main. Nil-safe:
// before wiring, all surfaces render (historical behavior).
func SetSignupVisibility(f func() bool) {
	signupVisible = f
}

// SignupVisible consults the wired closure (defaults to visible).
func SignupVisible() bool {
	if signupVisible == nil {
		return true
	}
	return signupVisible()
