Module media_query_transform 

Media query transformation functionality.

Implements the “last media query wins” transformation logic for CSS-in-JS. This ensures proper specificity handling when multiple media queries target the same properties.

This implementation provides media query transformation:

1. DFS traversal of the style object
2. At depth >= 1, apply negation-based media query transformation
3. Use pure AST manipulation, not range-based logic

Functions

are_media_queries_disjoint 🔒

Check if all media queries represent disjoint width/height ranges

combine_media_query_with_negations 🔒

Combine media query with negations - matches JS combineMediaQueryWithNegations exactly

create_object_from_key_values 🔒

Helper function to create ObjectLit from key-value pairs

dfs_process_queries_with_depth 🔒

DFS traversal with depth tracking - matches JS dfsProcessQueries exactly

extract_width_height_range 🔒

Extract width/height range from a media query if it’s a simple range

key_value_to_str 🔒

Helper function to extract key as string from KeyValueProp

last_media_query_wins_transform

Main entry point - equivalent to lastMediaQueryWinsTransform in JS

last_media_query_wins_transform_internal

Internal helper function for backwards compatibility with existing tests This preserves the old Vec -> Vec signature for internal use

normalize_media_query_syntax 🔒

Just normalize media query syntax without applying negation logic

ranges_overlap 🔒

Check if two ranges overlap

transform_media_queries_in_result 🔒

Transform media queries in the result object - matches JS logic exactly
