Changes: - the composer and user messages now have a colored background that stretches the entire width of the terminal. - the prompt character was changed from a cyan `▌` to a bold `›`. - the "working" shimmer now follows the "dark gray" color of the terminal, better matching the terminal's color scheme | Terminal + Background | Screenshot | |------------------------------|------------| | iTerm with dark bg | <img width="810" height="641" alt="Screenshot 2025-09-25 at 11 44 52 AM" src="https://github.com/user-attachments/assets/1317e579-64a9-4785-93e6-98b0258f5d92" /> | | iTerm with light bg | <img width="845" height="540" alt="Screenshot 2025-09-25 at 11 46 29 AM" src="https://github.com/user-attachments/assets/e671d490-c747-4460-af0b-3f8d7f7a6b8e" /> | | iTerm with color bg | <img width="825" height="564" alt="Screenshot 2025-09-25 at 11 47 12 AM" src="https://github.com/user-attachments/assets/141cda1b-1164-41d5-87da-3be11e6a3063" /> | | Terminal.app with dark bg | <img width="577" height="367" alt="Screenshot 2025-09-25 at 11 45 22 AM" src="https://github.com/user-attachments/assets/93fc4781-99f7-4ee7-9c8e-3db3cd854fe5" /> | | Terminal.app with light bg | <img width="577" height="367" alt="Screenshot 2025-09-25 at 11 46 04 AM" src="https://github.com/user-attachments/assets/19bf6a3c-91e0-447b-9667-b8033f512219" /> | | Terminal.app with color bg | <img width="577" height="367" alt="Screenshot 2025-09-25 at 11 45 50 AM" src="https://github.com/user-attachments/assets/dd7c4b5b-342e-4028-8140-f4e65752bd0b" /> |
