Spells, constellations, and backgrounds

The spell list now opens in a sensible default state. Previously, entering the menu could leave spells collapsed or in an unclear mode — it should now be immediately readable.

Constellations have received a visual update. The layout is cleaner and more consistent with the rest of the UI.

Class-themed backgrounds now appear across hub and menu screens. Several sections that previously had placeholder or mismatched art now show the correct visuals for your character's class.
