-//! Blocker block-screen UI.
+//! Blocker GUI: Calm Block Screen and Schedule Manager.
 //!
-//! Placeholder. No UI toolkit is bound here yet — see ADR-6 in
+//! Built with egui/eframe per ADR-6.
-//! `docs/DECISIONS.md` for why that is an open decision rather than an oversight.
-//!
-//! # What this process is for
-//!
-//! It is a short-lived, separately-executable window. The daemon stays resident
-//! and small; this launches when a block fires and exits when it lifts. Keeping
-//! them separate means a crash in window rendering cannot take enforcement down.
-//!
-//! # Design constraints that will apply (docs/UX-BLOCK-SCREEN.md)
-//!
-//! - Calm, not punitive. No red-alert styling, no shaming copy, no streak
-//!   counters. The screen exists to end an argument with the user's own
-//!   intention, so it must lower arousal.
-//! - It always states which schedule blocked and when it lifts. Uncertainty is
-//!   what makes people fight the tool.
-//! - It is never a dead end: a plain-looking "How to turn this off" entry is
-//!   always present, including under Strict Mode (CLAUDE.md section 1.5.4).
-//! - Under Strict Mode the *absence* of a bypass button is stated explicitly.
-//!   Silently missing controls read as a bug and breed distrust.
