Pixel Density (DPR)
High pixel density surfaces icon and text clarity issues.

Viewport Size (CSS Resolution)
The CSS viewport defines how media queries, layout breakpoints, and responsive components behave.
For Xiaomi 15T, the CSS viewport measures:

- Height: 924 px
ℹ️ The visible height can vary slightly depending on the browser UI (Safari, Chrome, etc.).
Some analytics platforms only display the physical screen resolution (see below) instead of the CSS viewport size, so keep that in mind when interpreting results.
