Unified link colours and heatmap filters
Unified entity link colours - all entity links across the platform now use a consistent teal colour instead of per-entity colours (emerald for characters, terracotta for books, blue for series, etc.). Entity dots next to names still use their distinct colours so you can tell entity types apart at a glance. This also applies to the navigation header, breadcrumbs, search results, and all detail pages.
Heatmap search and filtering - the character appearance heatmap on series pages now has the same search bar and role filter as the table and cast views. Results are paginated at 20 characters per page.
Ability type universe labels - the universe name (e.g. "Cosmere" under "Allomancy") now appears in the abilities table for curators and contributors, matching the read-only view that was already showing it.
Timeline entity dots - series and book links in the character story arc timeline now have coloured entity dots for visual distinction.
Custom tooltips - native browser title tooltips replaced with styled custom tooltips across public pages: heatmap cells, cast overview book names, story arc appearance icons and action buttons, group table truncated lists, and character browse sort buttons. Story arc action tooltips dismiss automatically when menus open.
