The Global Supply Chain Designer

Help me design a supply chain that spans multiple countries.

The product and where inputs/markets are: [DESCRIBE]
Priorities: [COST / SPEED / RESILIENCE / RISK]

Provide:
1. Where to source, make, and hold inventory given cost, tariffs, and
   lead times
2. The trade-off between low-cost distant sourcing and resilient nearer
   sourcing
3. The risks (geopolitical, currency, logistics, concentration) and how
   to reduce them
4. The tariff, customs, and trade-agreement factors that affect the
   design
5. A recommended structure and the biggest vulnerability to manage

Balance cost efficiency against resilience — recent history shows the
cheapest global chain isn't always the smartest. Flag trade/tariff
specifics to verify currently.
