foundation_auth_ui
WHY: WASM UI components for the authentication flow — login, register, MFA, password reset, account management, and passkey enrollment.
WHAT: Page components built on foundation_wasm_ui (reactive html!,
signals, DOM ops over a wire) and foundation_ui_components (headless
primitives: input, button, dialog, tabs, etc.).
HOW: Each page is a fn(&Context, &SharedInstructionReceiver, ...) -> Html
that self-mounts and drives API calls via primal:on* event handlers.
