Phase 1: Determine Scope

Read the argument:

• System name → focus profiling on that specific system
• full → run a comprehensive profile across all systems

Phase 2: Load Performance Budgets

Check for existing performance targets in design docs or CLAUDE.md:

• Target FPS (e.g., 60fps = 16.67ms frame budget)
• Memory budget (total and per-system)
• Load time targets
• Draw call budgets
• Network bandwidth limits (if multiplayer)
