Flow walkthroughs

End-to-end arcs, in the order most integrators implement them:

• Wallet whitelisting — register a minter wallet and activate its on-chain grant. The wallet must be active before you start a mint or burn flow.
• Onramp intent — fiat → crypto. Creates an intent, returns payment instructions.
• Offramp intent — crypto → fiat. Creates an intent, returns burn instructions.
• Burn signing — sign the staged user_burn in the user's wallet and submit back to Nora.

Start with Core concepts if you haven't already — every flow relies on the same X-API-Key auth and idempotency-key conventions.
