`usb_cdc_transport` has a permanent transport task and TinyUSB callbacks. Attached plus host DTR asserted is treated as open. Opening starts the serial service if necessary, creates the `usb-cdc` broker client, and opportunistically requests writer ownership; otherwise USB observes.
TinyUSB callbacks enqueue/copy data and state; the transport task owns broker lifecycle and forwarding. The callback caches the latest supported host line coding regardless of current writer state; the task applies it only while USB is writer, the serial service is running, and TX is empty. The pending value is discarded when the CDC session closes and is not automatically persisted.
TinyUSB callbacks enqueue/copy data and state; the transport task owns broker lifecycle and forwarding. The line-coding callback records the latest host setting for diagnostics only. It never reconfigures UART1: physical framing and speed remain controlled by the explicit serial configuration, regardless of USB writer ownership.
