DeviceSize enum

The current viewport-width / layout class of the window.

This is the layout width class the UI should adapt its structure to (narrow / medium / wide), derived from the ResponsiveScope's width via classify. It is deliberately orthogonal to two other device concepts in this package, which it must not be conflated with:

  • DevicePlatform — the operating system (iOS / Android / web / macOS / Windows / Linux). For "is this a phone OS?" use DevicePlatform, not DeviceSize.
  • DeviceFormFactor — the physical device form factor (phone / tablet / desktop / browser), used server-side for notification-delivery prioritization and not barrel-exported. It shares the tablet / desktop names with DeviceSize (and phone ≈ mobile), but it describes the hardware, whereas DeviceSize describes the current window width.
