+//! STM32F7 peripheral drivers used by Kaptan boards.
+//!
+//! This crate is organized by MCU variant and peripheral route. A board chooses
+//! an MCU feature, owns its pin muxing and RTIC interrupt graph, then composes
+//! the typed peripheral drivers from the selected module. Generic telemetry
+//! policy and frame ownership deliberately do not belong here.
