[counterintuitive] Putting all task instructions and context into the system prompt assuming it has magical weighting

Distribute instructions logically; use the system prompt for persistent persona/safety/format rules, and use the user message for the specific task and immediate context.

Journey Context:
Early models heavily weighted the system prompt, so developers crammed everything there. Modern models treat system and user messages more equally in terms of instruction following. Overloading the system prompt with task-specific context can actually cause the model to ignore persistent rules due to attention dilution. Keep the system prompt for global constraints and use user/assistant turns for the actual workflow.
