* FocusModePage is the dedicated focus mode interface accessible from the bottom navigation and via a floating action button on the home dashboard.
* The page centers a large FocusTimerRing widget — a circular countdown ring drawn with CustomPainter that drains smoothly as time elapses, with a subtle glow effect on the leading edge.
* FocusAmbientBackground renders a slow-moving gradient animation behind the timer to create a calming atmosphere during focus sessions. The gradient shifts between analogous colors derived from the dynamic color scheme.
* FocusProfileSelector displays available profiles as horizontally scrollable MD3 cards showing profile name, duration, and number of blocked apps.
* BlockedAppsList shows the apps blocked in the selected profile with app icons and names, plus a toggle to add or remove apps.
* FocusCompletionCard is a modal card shown on session completion with the session summary: total time, distractions, completion score, and an encouraging message.
* A breathing animation (focus_breathing.riv) can optionally be displayed during the session for mindfulness.
* The FAB on the home dashboard uses a custom animated icon that transitions from a target icon to a stop icon when a session is active.
* During an active session, the bottom navigation shows a subtle indicator on the Focus tab.
