// Changelog:
// v1.5.1 - Bug fix: Fixed @match directive for contacts.google.com to support
//          Google Workspace accounts with /u/1/ paths (hovercards now work on all accounts)
// v1.5.0 - Major rewrite: Removed jQuery dependency, now uses pure vanilla JavaScript
//          No longer requires separate TrustedHTML bypass script
//          Uses native DOM methods (createElement, createElementNS) instead of innerHTML
//          Smaller, faster, and bypasses TrustedTypes restrictions without workarounds
