+- Replaced the "Library — Per Day" section on the Stats → Trends page with a "Library — Summary" section. The new section shows a top-10 watch-time leaderboard chart and a sortable per-title table (watch time, videos, sessions, cards, words, lookups, lookups/100w, date range), all scoped to the current date range selector.
