Summary

• Use the viewer's selected --accent theme color for hover and keyboard-focus highlights on generated printed-contents and inferred-reference links.
• Detect visible http:// and https:// addresses that were printed as PDF text but lack native PDF hyperlink annotations.
• Recognize URLs spanning adjacent PDF.js text fragments, without combining separated lines or visually distant text.
• Strip trailing sentence punctuation while retaining balanced parentheses within URLs; reject malformed URLs and non-HTTP(S) schemes.
• Render detected URLs as real links that open in a separate tab with noopener noreferrer; keep the document's original text appearance.
• Suppress generated URL overlays when a native PDF hyperlink annotation overlaps any portion of the URL, including fragmented URLs. Native PDF and LaTeX links remain unchanged.

Tests and verification

• Add tests for the accent hover/focus styles and independence from native annotations.
• Add tests for HTTP(S) recognition, punctuation, balanced parentheses, unsupported schemes, invalid URLs, fragmented text, URL boundaries, safe anchor attributes, and native-link exclusion.
• Validated URL parsing and generated anchor behavior using isolated JS execution with mock browser geometry.
• Verified the commit's tree differs from its parent and the expected source/test blobs are present.
• Full repository npm test and extension build have not been run locally.
