- Widget is now a bottom-anchored dock spanning the content width (max-width 1200px, rounded top corners, bg-secondary, upward shadow) instead of a floating corner box. - Drop the closed state and ✕ button — widget is always present, matching KnowledgeView's pattern. Collapsed = input-only dock, expanded = full ChatPanel above the input. - Grid ratio 1fr:2fr → 0.85fr:2.15fr so tasks get a touch less room and notes a touch more. - Workspace note-rail (the notes picker column inside the editor) widens from 155px to 200px so note titles breathe.
