pub fn invalidate_caches()Expand description
Reset all process-wide caches so the next call to system_is_dark(),
prefers_reduced_motion(), or system_icon_theme() re-queries the OS.
Call this when you detect that the user has changed system settings (e.g., dark mode toggle, icon theme switch, accessibility preferences).
The detect_*() family of functions are unaffected — they always query
the OS directly.
