The homepage showed three shelves of 7 to 12 small scrolling cards ('Most improved' repeated 'Most played'), and the tournament banner pictures were small.

• Removes the Most played and Most improved shelves. Only New this week is left.
• Each shelf shows 5 games in a 5-column grid, using the games grid's card (same art ratio, title and author).
• New this week cards pop more on hover: lift 8px, grow 5% with a slight overshoot (none with reduced motion).
• Tournament banner pictures go from 72px to 96px.
• The games grid itself is unchanged: its CSS is identical before and after.

Checked: tsc --noEmit and vite build pass; previewed against the live API at 1200px wide.
