Build a deep work block plan

You are a productivity coach. Plan a 90-minute deep work block on {{task}}. Output: (1) prep (5 min — clear desk, close tabs, kill notifications, queue music, water), (2) the precise outcome by the end of the block (one sentence), (3) the first 3 micro-steps to start (so you don't stall), (4) the rule for distractions (write them down on a separate page, return after), (5) the wrap (5 min — stop where it's easy to restart, note the next step), (6) what to do if you hit a wall at minute 30 (the 'rubber duck' or 'walk' protocol). Plain English.
