	    - Per-thread LVGL contexts on an RTOS (FreeRTOS, Zephyr, etc.)
	    - Hot-swappable or sandboxed UI instances

	  When enabled, every LVGL internal access to global state goes
	  through LV_GLOBAL_CUSTOM() instead of a static variable. You
	  must implement 'lv_global_t *lv_global_default(void)' to return
	  the correct instance for the current context (e.g. by thread-local
	  storage or a guarded pointer switch).

	  Returning NULL from that function is safe; LVGL will treat the

	  Optional header to override LV_ATTRIBUTE_* macros for your platform.
	  Leave empty to use defaults (all expand to nothing).

	  Create a header file and set this to its path, e.g. "my_lv_attr.h".
	  The following macros can be defined in it:

	  LV_ATTRIBUTE_MEM_ALIGN
	    Where memory needs to be aligned (e.g. with -Os, data may not be
	    aligned to the required boundary by default).
	    e.g. __attribute__((aligned(4)))

	  LV_ATTRIBUTE_TICK_INC
	    Applied to lv_tick_inc(). Often called from a timer ISR, so fast
	    memory placement can reduce latency.
	    e.g. __attribute__((section(".itcm"))) or __ramfunc (IAR)

	  LV_ATTRIBUTE_TIMER_HANDLER
	    Applied to lv_timer_handler().
	    e.g. __attribute__((section(".itcm")))

	  LV_ATTRIBUTE_FLUSH_READY
	    Applied to lv_display_flush_ready(). Often called from a DMA or
	    display ISR.
	    e.g. __attribute__((section(".itcm")))

	  LV_ATTRIBUTE_SYNC_READY
	    Applied to lv_display_sync_ready(). Similar to FLUSH_READY, useful
	    when called from an ISR context.
	    e.g. __attribute__((section(".itcm")))

	  LV_ATTRIBUTE_LARGE_CONST
	    Applied to large read-only arrays such as font bitmaps. Use to place
	    them in a specific flash region or external memory.
	    e.g. __attribute__((section(".ext_flash")))

	  LV_ATTRIBUTE_LARGE_RAM_ARRAY
	    Applied to large arrays allocated in RAM.
	    e.g. __attribute__((section(".ext_ram")))

	  LV_ATTRIBUTE_FAST_MEM
	    Applied to performance-critical functions to place them in faster
	    memory such as ITCM or SRAM.
	    e.g. __attribute__((section(".itcm"))) or __ramfunc (IAR)

	  LV_ATTRIBUTE_EXTERN_DATA
	    Prefix for all global extern data declarations. Useful for placing
	    shared data in a named section or applying export attributes.
	    e.g. __attribute__((section(".shared_mem")))

	  LV_EXPORT_CONST_INT(int_value)
	    Exports an integer constant to a language binding API such as
	    MicroPython. Called for all constants in the form LV_<CONST>.
	    Leave undefined if not using a binding.
	    e.g. mp_rom_map_elem_t entry = {MP_ROM_QSTR(MP_QSTR_##int_value), MP_ROM_INT(int_value)}
