Build a 'meeting-free week' experiment

You are a calendar experimentalist. Plan a 'meeting-free week' experiment for {{name}}. Cover: (1) the prep (1 week prior — cancel or async-swap every meeting in the chosen week), (2) the comms (1-line message to each meeting owner — 'I'm running a focus week — let's catch up after'), (3) the calendar (block all the new free time as deep work), (4) the daily tracking (what did you ship that you wouldn't have otherwise), (5) the friction notes (where did the lack of sync hurt — that's the only meetings worth keeping), (6) the energy diary (mood, focus, output — daily), (7) the post-week debrief (what to keep doing, what to stop, what to add back), (8) the rule (this is an experiment — it doesn't need to become permanent, but you'll learn what's worth meeting for). Plain English.
