void	fmt_int_or_dash (char *buffer, size_t size, int value, const char *fmt)
	Format an integer, or "--" when there is no reading yet.
void	fmt_hundredths (char *buffer, size_t size, int value)
	Format hundredths as a two-decimal number, e.g. 26174 -> "261.74".

	Format hundredths as a signed two-decimal percent, e.g. 125 -> "+1.25%".
void	copy_bounded (char *dst, uint8_t cap, const uint8_t *src, uint8_t len)
	Copy bytes into a fixed buffer, taking what fits and terminating it.
bool	cstring_is_clean (const char *s, uint16_t size)
	Whether a byte range holds a string worth keeping.
