What’s new

Each class now shows its real icon glyph on the party screen and class picker — no more two-letter abbreviations.
The draw screen shows the full class portrait as a soft background behind the cards, so every character feels distinct.
Locked classes still stay spoiler-safe: you'll see a grey silhouette of the icon instead of the colored version.
