Statement
The icon theme switcher shall cycle through modes in the order system -> light -> dark -> system on each click, display the icon corresponding to the current preference, and update its aria-label and title to reflect the active mode.
Rationale
Predictable cycle order and self-describing labels ensure the control is understandable without adjacent explanatory text, satisfying accessibility requirements for icon-only interactive controls.
