Module snapshot 

Canonical layout dumps for snapshot tests. Canonical layout dump for core WidgetConfig snapshot tests.

Constants

CORE_ELEMENTS

Core elements present on every platform with preserved IR semantics. Pixel-identical rendering is not guaranteed — see degraded cells in the capability matrix (image.systemName, Windows zstack / shape, …).

EXTENDED_ELEMENTS

Extended / best-effort elements (platform-dependent).

Functions

dump_config

Dump a config to a stable JSON tree (nulls omitted, keys sorted via serde_json Map order of insertion — we insert in a fixed order).

is_core_element

true when ty is in CORE_ELEMENTS.
