//! Tests for [`TextField`]'s runtime password-reveal affordance.
//!
//! A password field masks its characters unless a bound "reveal" cell forces
//! plaintext. This exercises `masking_active` against the public builders that
//! back the demo's eye-toggle button, using real production code paths.
