//! RPC 单笔解析示例：
//! - **默认**：本地 ix 路径（便于打印完整日志等）。
//! - **对齐 sol-parser-sdk**：`SOL_PARSER_SDK_RPC=1` 时对同一笔 RPC 响应使用 `parse_encoded_rpc_transaction_as_streamer_events`。
//! Single RPC transaction parse example:
//! - Default: SDK-backed parsing through `parse_encoded_rpc_transaction_as_streamer_events`.
//! - Debug compare: set `STREAMER_LOCAL_IX=1` to run the local instruction path.
//!
//! 亦可直接使用 crate 根的 `fetch_rpc_transaction_as_streamer_events_async`（单独 RPC 拉取 + 对齐解析）。
//! You can also call `fetch_rpc_transaction_as_streamer_events_async` from the crate root
//! when you want the helper to fetch and parse by signature.
//!
//! 环境变量：`SOLANA_RPC_URL`（可选，默认 mainnet 公共 RPC）。
//! Environment: `SOLANA_RPC_URL` (optional, defaults to the public mainnet RPC).
