-# Story 48: Two-Column Layout — Chat Left, Panels Right
-
-## User Story
-
-As a user, I want the chat and panels to sit side by side so that the panels don't crowd out the chat history.
-
-## Acceptance Criteria
-
-- [ ] Chat header spans the full width across the top
-- [ ] Below the header, the layout splits into two columns:
-  - **Left column**: Chat messages (scrollable) with chat input pinned at the bottom
-  - **Right column**: All panels (Agent, Review, Gate, Todo, Upcoming) stacked vertically, independently scrollable
-- [ ] The left column takes roughly 60% width, right column 40%
-- [ ] On narrow screens (below ~900px), the layout falls back to a single column with panels stacking below the chat
-- [ ] Chat input is no longer affected by panel height — it stays pinned at the bottom of the left column regardless of how many panels are expanded
-
-## Out of Scope
-
-- Resizable/draggable column divider
-- Collapsible right panel sidebar toggle
-- Removing or consolidating panels
