Glossary entries that connect themselves, and thousands of new group memberships
Glossary entries now connect themselves - every glossary entry page now builds its own "Related" lists automatically from the entry's text: the characters, groups, places and other glossary entries it mentions, neatly organised by type. There's also a new "Mentioned in" list showing every entry that references this one - so from a big topic like Allomancy you can hop to every entry that touches it, and from a small entry you can find your way back to the big ones. No more hand-kept "see also" lists that drift out of date.
Glossary text can point at species, origins and occupations - when an entry mentions a species like the Fjerdans or an occupation like witch-hunters, it can now link straight to the matching character browse page - and that page arrives already filtered to the right world, with a clear note and a "view all" link if you want the cross-world view.
Far more characters show their groups - a long verification push has gone through every world in the library adding characters' groups - houses, orders, crews, guilds and factions - checking each membership against the books before recording it. Coverage has gone from about one character in six to nearly one in two. Memberships that are reveals or twists are spoiler-aware: they stay hidden until your reading progress reaches the moment the book makes them explicit.
Tidier glossary lists - glossary lists now ignore "The" when sorting, so "The Amber Spyglass" files under A rather than T - in the A-Z index, in search results, and in the new related lists. We also merged a duplicate entry that had crept in, and the old link quietly forwards to the right place.
