https://snowflake.torproject.org/embed is confusing

embed.html should be the go to for embedding snowflake badges in webpages but it currently has a couple of problems,

1. No description, nothing to suggest to the lambda visitor about what to do.

2. Clicking on the badge redirects to the options page hosted in torproject.org, but this means that users who have first-party isolation manually enabled (as can be done in Firefox) won't be able to enable it on the page where embed.html is embedded.

Ideally what should be done is:

1. Small description ("Do you want to help censored users access the Tor network?") with a snowflake logo.

2. If user clicks on yes, then in that same iframe there's some JS check to see if WebRTC is disabled, if it is inform the user that WebRTC is necessary and perhaps add a link on how to enable it back.

3. If WebRTC is enabled, then load up snowflake.js and modernizr.js. Description should contain if the connection to the broker is done and is waiting for a client request, and if it is then maybe the logo should change as well as the description. (Since everything is done on the same page then there won't be any problems with first party isolation -- except with 3rd party cookies disabled)

Ideally it should be easy to embed into webpages if what's above is done, and should be small enough.
