Data Structures
struct	woz_sink
	Small bounded sink so cbpprintf can render into a stack buffer. More...

Functions
static log_timestamp_t	woz_timestamp_get (void)
	Advance + read the 64-bit cycle accumulator (irq-safe; any context).
static void	woz_wrap_sample (struct k_timer *t)
	Periodic sampler so a CYCCNT wrap is never missed during console idle.
static int	woz_sink_out (int c, void *ctx)
	Sink callback for formatted output: append one character to the buffer if space remains.
static void	woz_sink_str (struct woz_sink *s, const char *str)
	Append a null-terminated string to the sink buffer one character at a time, stopping at end of string or exhausted buffer space.
static const char *	module_color (const char *name)
	Stable per-module colour from a name hash (djb2).
static void	woz_msg_format (const struct log_output *output, struct log_msg *msg, uint32_t flags)
	Render one message as SEC.NS module message, or delegate hexdumps.
static int	woz_logfmt_init (void)
	Initialize the DWT cycle counter and log formatting on startup.
