Dgetsylver#79 — Architecture diagram in root README - Add docs/diagrams/architecture.svg: SVG flow diagram showing User → Wallet → Frontend → Soroban RPC → Blend Pool → b/d Tokens - Create README.md embedding the diagram with a layer description table, quickstart instructions, and links to existing docs - Diagram uses inline CSS classes for fill/stroke so it renders correctly on both GitHub dark and light themes Dgetsylver#89 — Rate-limit RPC calls from frontend - Upgrade withRetry() in frontend/src/blend.ts: - Increase default retries from 2 to 4 - Switch from fixed delay to exponential backoff (baseDelay × 2^attempt) - Add up to 300 ms of random jitter per attempt to spread retry storms - Detect HTTP 429 responses (status field and message string) and emit a console.warn with the back-off duration when throttling triggers - Wrap every bare server.getAccount(), server.getLatestLedger(), and server.simulateTransaction() call in withRetry() across all transaction builders: buildApproveXdr, buildOpenPositionXdr, buildCloseSubmitXdr, buildRepayXdr, buildWithdrawXdr, buildClaimXdr, buildIncreaseLeverageXdr, buildDecreaseLeverageXdr, buildResupplyXdr Closes Dgetsylver#79 Closes Dgetsylver#89
