/**
 * @file types.h
 * @brief Portable integer types and SPI/storage configuration types for SPP.
 *
 * Provides width-exact integer typedefs derived from <stdint.h> and <stdbool.h>
 * so that SPP code is independent of compiler-specific type widths.  Also
 * defines configuration structs shared between the HAL interface and port
 * implementations.
 *
 * Naming conventions used in this file:
 * - Portable base types:  spp_<sign><width>_t   (lowercase snake)
 * - Config struct types:  SPP_<Name>_t           (uppercase prefix, CamelCase)
 * - Enum / constant values: K_SPP_*
