/**
 * Structured transport error for the direct Google Sheets API outbound
 * provider. Extracted from the adapter (where it was co-located with the
 * provider's request-boundary helpers) into the contracts leaf: the shared
 * `classifyTransportOutcome` boundary must classify adapter-thrown errors by
 * class identity, so the class has to live where both sides can see it.
 *
 * The transport converts gaxios/network failures into
 * `GoogleSheetsApiTransportError` with explicit HTTP-status and stable-code
 * presence so `classifyTransportOutcome` can decide between a proven
 * pre-mutation rejection and an ambiguous delivery without reading raw SDK
 * error objects. (P8-B: contract-ish symbol moved with the transportOutcome
 * layer; the adapter module re-exports it so existing adapter import paths
 * stay valid.)
