// Canonical layout breakpoints for Chanora.

//
|
||
// Aligned with Material 3 adaptive layout guidance:
|
||
// compact < 600dp — phone, narrow tablet
|
||
// medium 600–1023 — tablet portrait, small desktop window
|
||
// expanded ≥ 1024dp — desktop, tablet landscape
|

|

// 1024dp was chosen as the expanded threshold based on production app

// ≥ 1024px), and Rocket.Chat (contextual bar persistent at lg/1024px).
