Fixed potential prototype pollution: Properties starting with _PROTO_ are now stripped from objects before processing (search for "_PROTO_" in the wE6 function)
Fixed apiKeyHelper error handling: Clearer error messages when API key helper fails or takes too long (search for "apiKeyHelper failed:" and "apiKeyHelper is taking a while")
Data URL byte-size estimation now correctly handles percent-encoded base64 padding characters in data URIs (search for Lc1 function at line ~37105)
