## Story 002: Take a break and return to focus

**Persona:** Yuki, 28, a writer who uses pomodoro to structure her writing day. After a focus session, she needs a clear signal that it's okay to step away, and a timer to make sure her break doesn't stretch into an hour of scrolling.

**Situation:**

Yuki's first 25-minute session just ended. She got the notification. Now she wants to know how long her break is, and she wants a timer so she doesn't lose track of time during the break.

**Need:**

As Yuki, I want the app to automatically offer me a 5-minute break after a session ends, with its own countdown timer, so that I know when to get back to work.

**Acceptance:**
- After a session completes, I see a break timer appear automatically (5 minutes by default)
- The break timer counts down just like the session timer
- When the break timer finishes, I receive a notification that it's time to start the next session
- I can dismiss the break notification and start a new session manually whenever I'm ready

**Tier:** core

**Confusion-flags:**
- Should the break timer auto-start, or require a click? Auto-start is frictionless but might startle someone mid-conversation.
- What if the user wants to skip the break or take longer? The interface needs to support that without feeling like the app is fighting them.
