+## Work State

+### Completed this session
+- **Scroll-position fighting** — `scrollToTop()` now respects `_userScrolledAway` flag (100px threshold), skips auto-scroll when user is reading older content. `resetScrollLock()` called on new messages.
+- **401 error cascade** — `SESSION_TIMEOUT_SECONDS` bumped 90→3600 (1 hour). All 10 unprotected `authFetch` calls wrapped in try/catch.
+- **Token counter** — removed localStorage persistence; resets to 0 on page refresh.
+- **Ctrl+Enter for web search** — Shift+Enter now inserts newline (universal convention), Ctrl+Enter triggers search.
+- **Search button styling** — `search-btn` now matches `send-btn` font/font-size/weight. Label: "web 🔍".
+- **User message toolbar** — copy/print/save toolbar added to user messages (was assistant-only).
