What are interventions?
An Intervention is when a Browser opts for:

• an intentional deviation from a behavior that developers expect and/or rely on,
• which is motivated by the desire to fulfill an important user need.

Because of its nature, it must be done sparingly and with extreme care to not only achieve but also sustain a positive outcome.
