Functions
FASTLED_FORCE_INLINE bool	fl::isr::is_aligned (const void *ptr, size_t alignment)
	Check if a pointer is aligned to a specific byte boundary.
FL_OPTIMIZE_FUNCTION FL_IRAM FASTLED_FORCE_INLINE void	fl::isr::memcpy (void *FL_RESTRICT_PARAM dst, const void *FL_RESTRICT_PARAM src, size_t num_bytes)
	ISR-optimized memcpy with alignment detection and switch dispatch.
FL_OPTIMIZE_FUNCTION FL_IRAM FASTLED_FORCE_INLINE void	fl::isr::memcpy_16 (u16 *FL_RESTRICT_PARAM dst, const u16 *FL_RESTRICT_PARAM src, size_t count)
	ISR-optimized 16-bit block copy for 2-byte aligned memory.
