Which client-side page source edits can get run on the gateway from the browser?

In the case of the JS via markdown that enabled the RGB picker in another thread, what can the client-side browser source page edits run on the gateway?

Nothing.  
Perspective, by design, doesn't 'trust' the client. At most, the client-side can indicate that an event happened, and _if the Gateway would already allow that event to happen_, it will be invoked on the gateway.
