The Arcane Library holds 3,072 books distributed across 31 thematic sections. Your job is to reshelve them. Books arrive on a conveyor in randomized order and must be sorted by author’s era, magical classification, and the shelf color-coding system the previous librarian left behind. The color system has no legend.
Assemble mode lets you group books into temporary stacks for cross-referencing before shelving. Insight mode briefly reveals the hidden classification of any book you hover over, at the cost of one Insight point per use. Auto-Shelving activates after you correctly shelve forty books in a row, moving the next ten automatically.
Patron requests arrive during evening hours and require you to locate specific books already shelved elsewhere in the library, temporarily disrupting any active sorting momentum. The library has a closing time. You keep your progress between sessions but lose any unsorted books left on the conveyor at closing.
