MudEngine Part 6: Multiplayer

Step 16 / 18

CSS Additions

The multiplayer UI needs additional styles for the game layout, player indicators, sidebar, D-pad controls, clickable room cards, and name screen.

Append these styles to assets/main.css. Keep the existing styles from Part 4 (the grid, description panel, etc. are reused).

The .cell.clickable rules bring back the Part 5 click-to-move affordance: a pointer cursor, a subtle border, and a blue hover glow so players can see which rooms they can move into. .game-layout:focus removes the browser's focus ring — the game area is focusable so the keyboard shortcuts work, but we don't want an ugly outline around the whole layout.
