Text across the site is bigger. The base size went up, the smallest descriptions went up a step on top of that, and the body font is now Barlow, the full-width version of the narrow font we used before. Grey secondary text is lighter, so it no longer reads as a second, fainter kind of small.
Cards and sections stand out. The page background, the section bands and the cards used to be three very close shades of navy; now each one is clearly lighter than the one beneath it, so the home page and your profile read as distinct blocks.
Matches look exactly as they did. The in-match HUD keeps its own sizes, which are tuned around the arena.
