Problem
The composer textarea autosizes only up to 132px (Composer.tsx line ~35) then scrolls internally. Writing or reviewing a long multi-paragraph prompt on a phone is cramped.
Suggested fix
Add an "expand" control that opens a full-screen editor sheet for composing/reviewing long prompts before sending.
