   LESSON LEARNED: Don't fight the framework
   After trying position:fixed with manual sidebar calculations, the solution
   was simple: let Chainlit handle layout, just remove the obstacles.
   1. margin-top: auto - flexbox pushes to bottom, stays in document flow
   2. Kill Chainlit's spacer div - it creates artificial gap
   3. Remove parent padding - flush to bottom edge
   Result: Works with sidebar, mobile, resizing - no positioning hacks needed.
