This is a temporary test post created specifically to check image quality in the Dapper Diaries card layout.
The image source is a 1024 × 1536 portrait file already hosted on the Tasker & Shaw website, so it should remain sharp in the 3:4 card crop.
Image quality test
If this card looks crisp on desktop, we know the card layout itself is working correctly and the earlier blur came from the tiny temporary JPEG files rather than the blog design.
