Adds Curios support for the Ars Nouveau spell book, allowing it to be equipped in a Curios slot instead of taking up inventory or hotbar space.
While the book is equipped, it can still be used normally, including casting spells directly from the Curios slot using the dedicated “Cast Slotted Spellbook” keybind, which is set to r by default. The radial menu also has its own separate keybind (g by default) when the spellbook is equipped, making it easy to access and swap spells without holding the book in your hand.
Designed to stay simple, lightweight, and fully focused on compatibility with Ars Nouveau and Curios while keeping your hotbar free for other items
