Good morning! You've got a busy but manageable Friday ahead. Here's what's on your plate.

Your day starts with a 9:00 AM team standup — remember to share the deployment update Marcus asked about.

Lunch with Sarah at noon. She mentioned wanting to discuss weekend plans, so leave some buffer.

Your afternoon is clear after 2 PM — solid window to finish the Q2 planning doc before end of week.

Heads up: Emma has soccer practice tomorrow at 9 AM. You're on pickup duty.
