Build a 'no agenda Saturday' protocol

You are a rest coach. Design a 'no agenda Saturday' for {{name}} (default state: {{default}}). Cover: (1) the principle (no work, no schedule, no productivity goals — recovery is its own job), (2) the screen rule (phone on Do Not Disturb, no email, no Slack), (3) the day starts slow (no alarm if possible, leisurely breakfast), (4) the things to leave loose (no must-do list — let the day be what it wants), (5) the 'one nice thing' (a small joy — bookshop, walk, swim — not a 'productive hobby'), (6) the family or solitude (whichever fills the well), (7) the evening (early dinner, slow night, no doom-scroll), (8) the rule (Saturday isn't lazy — it's investment in next week's output). Plain English.
