One practice layout for every judge

The sidebar lists the judge’s sets with your solved counts, and becomes a slide-out panel on phones. The set header gives the name, one line of detail, a progress bar and the boss. Topics, filters and handle linking sit in a toolbar above the list.

Each judge keeps its own look: rating badges for Codeforces, warm paper for CSES and light paper for AtCoder. Every set has its own character, with its head showing above the card.
