+"""Bridge (by Stripe) offramp provider — sole provider per plan.
+
+Docs: https://apidocs.bridge.xyz/
+Auth: REST with `Api-Key` header + `Idempotency-Key` header on POSTs.
+
+Bridge accepts crypto at a deposit address and settles USD to a
+pre-registered external bank account via RTP / FedNow / wire / ACH.
+Unlike Coinbase Prime (which is a two-step: sell on exchange, then wire
+withdrawal), Bridge is a single-transfer model: create a transfer, send
+coins to its deposit address, and Bridge handles the conversion + payout
+to the destination bank.
+
+Env vars:
+    BRIDGE_API_KEY                       — Bridge API key
+    BRIDGE_API_URL                       — default https://api.bridge.xyz
+    BRIDGE_RELAY_EXTERNAL_ACCOUNT_ID     — pre-registered RelayFi account id
+    BRIDGE_DEVELOPER_FEE_USD             — optional platform fee (defaults 0)
+
+Flow:
+    1. prepare_transfer(coin, target_usd_cents, rail, memo, idempotency_key)
+       → POST /v0/transfers — returns {transfer_id, deposit_address}
+    2. SHKeeper payout to deposit_address
+    3. Bridge auto-detects deposit, converts, wires USD to Relay via RTP
+    4. status(transfer_id) — poll until state='payment_submitted' | 'completed'
+
+Supported coins (BRIDGE_ACCEPTS — restricted to what Bridge takes):
+    USDC / USDT / BTC / ETH / SOL (and more) — drops XMR + MATIC/TRX/BNB/DOGE.
+    See `accepts_coins` below. If the SHKeeper webhook delivers an
+    unsupported coin, the orchestrator flips the job to state='manual'.
