New Features
* New overlay-based highlighting system that draws boxes around elements without modifying page CSS
* Smarter visibility detection that skips hidden elements (display:none, visibility:hidden, aria-hidden, zero-sized, clipped by overflow containers)
* Highlights now work on elements outside the viewport (visible after scrolling)
* Internationalized highlight labels in 19 languages
Bug Fixes
* Fixed phantom "invisible" highlights on hidden elements
* Fixed highlight functions not executing (constants now defined inside functions)

Bug Fixes
- Fixed an issue where the SEO report could appear completely empty right after opening the popup.
- Fixed a background error that could occur while browsing in Google Chrome (visible in the console as "Could not establish connection").
- Fixed structured data (rich snippet) parsing so pages using multi-type schema markup — e.g. schema.org types combining "ProfessionalService" and "Organization" in a single entry — no longer cause the entire rich snippet section to be skipped.
- Fixed page HTTP header detection (X-Robots-Tag, Strict-Transport-Security, Referrer-Policy, Alt-Svc, etc.) so it works reliably across all sites.
- Fixed the "locate on page" buttons so they no longer error out on pages where highlighting isn't available (e.g. browser settings pages, the extension store, or PDF viewer tabs).

Security Improvements
- Hardened how page content is displayed in the popup to prevent a specially crafted web page from injecting and running malicious code inside the extension.
- Hardened how sitemap links (from a site's robots.txt) are displayed, so a malformed or malicious robots.txt file can no longer be used to inject unwanted content into the popup.

No settings, permissions, or existing functionality were changed — this release is fixes only.
