Detailed Description

Boot banner formatter.

Formats a startup banner with app name, build info, MCU metadata, and audio configuration. Uses __has_include for optional headers so it works in both firmware and unit test builds.

Usage: #include <sbl/log/banner.hpp>

char buf[384]; int len = sbl::log::format_banner(buf, sizeof(buf), "hello-instrument", 48000, 48); SBL_LOG_OUTPUT::write(buf);

Gated behind SBL_BOOT_BANNER (default: 1). Set to 0 to disable.
