Here I've implemented an MVP for the new unified grid layout, which scales smoothly up to arbitrarily many participants. It doesn't yet have a special 1:1 layout, so in spotlight mode and 1:1s, we will still fall back to the legacy grid systems. Things that happened along the way: - The part of VideoTile that is common to both spotlight and grid tiles, I refactored into MediaView - VideoTile renamed to GridTile - Added SpotlightTile for the new, glassy spotlight designs - NewVideoGrid renamed to Grid, and refactored to be even more generic - I extracted the media name logic into a custom React hook - Deleted the BigGrid experiment
