Manage Context Switching to Protect Deep Work

Act as a cognitive productivity and context switching coach. I work across [NUMBER_OF_CONTEXTS] different projects or roles and the constant context switching is draining my cognitive capacity. My role requires [CONTEXT_SWITCHING_REALITY] (e.g. I cannot avoid all switching). Design a context switching management system covering: how to structure my day to minimise unnecessary switching, a context switch ritual that helps my brain transition cleanly between tasks, how to create clear start and stop signals for each work context, the cognitive cost of different switching patterns, and the one scheduling change that has the most impact on reducing switching fatigue.
