Research direction

Start by reading the Compose app structure and its existing unit test setup to find where shared UI helpers and tests belong. Add the size class enum and calculation using the stated Material3 width boundaries, then test values at and around 600dp and 840dp. Done means all boundary tests pass.

Description

enhancement good first issue
Summary

To support adaptive layouts across Desktop window resize events, introduce a window size class provider (Compact, Medium, Expanded) based on standard Material3 breakpoints (width < 600dp, 600-840dp, > 840dp).

Acceptance Criteria
  • Define WindowWidthSizeClass enum (Compact, Medium, Expanded).
  • Implement calculateWindowWidthSizeClass(windowWidthDp: Dp).
  • Add unit tests verifying breakpoint boundaries.
