Format browsing just got a visual upgrade

The format pages — Browse formats and a playgroup's Linked formats — now show each format as a card with real Magic card art, instead of a plain text list. Official formats like Commander, Modern, and Standard, along with custom and draft formats, each get a labeled card showing their kind at a glance. Formats without art yet fall back to a simple placeholder until one is set. Behind the scenes, site admins can now pick which card's art represents each format, the same way you already pick a card to represent one of your decks.
