Collateral and oracle exposure

Each token you're exposed to, and the market it backs. If that market breaks, this is how much the vault loses, in dollars and as a share of the vault. Open a row for the price feed, stress curve, and supply-cap detail. Below, the oracles those prices depend on and what is at stake if one is compromised.
