Live stream branding

[astrojuanlu]

We now have access to StreamYard 🎉

I already customised some aspects of the branding:

• Used one of the Zoom backgrounds
• An overlay icon on the top-right
• Used Kedro yellow for visual elements, with rounded corners

Some other elements could be added such as overlays. Here is information about sizes:

@stephkaiser Do you want to make further tweaks?

This is done! We can do further tweaks over time
