Responsive design notes
Use the viewport for layout decisions, the native resolution for asset planning, and the DPR when understanding how CSS pixels map to physical pixels.
Use viewport for CSS
Focus on 410 x 854 PX when planning breakpoints and layout widths.
Use resolution for assets
The native 2176 x 1812 PX resolution helps guide image export sizes and display sharpness.
Use DPR for scaling
A DPR of 2.33 XXHDPI means this screen maps multiple physical pixels to one CSS pixel.
