// Internal logging macros that route to `log` and/or `defmt` based on cargo
// features. If neither feature is enabled, the macros expand to no-ops while
// still consuming their arguments to avoid unused-variable warnings.
//
// Convention follows the embassy-* crates: both backends can be enabled
// simultaneously (each call fires through every enabled backend).
