Subject: [PATCH] Improve pain scale visual indicator for better clarity
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Change checkmark to down arrow (▼) for better visibility in PDFs
- Increase arrow size to 20px and make it bold
- Use white background for non-selected boxes for stronger contrast
- Add thick black border (3px) on selected level for emphasis
- Selected box shows colored background with white text
- Increase selected label text size and make it bold black
- Clear visual distinction between selected (value 2 vs 4) levels now
