NOIRADIX Studio & PixelArt v2.1.8

Highlights

• Moved the four approved directory links (SourceForge, VibeCodePicks, TeaserTrack and AlternativeTo) directly below the README verdict, with the official VibeCodePicks badge and existing official badges.
• Added the VibeCodePicks listing badge and SourceForge project link to the Studio About dialog and documented the directory listings in the documentation portal.
• Replaced stale, keyword-stuffed Studio metadata with concise descriptions of verified product capabilities; removed the unsupported meta keywords list.
• Updated Studio structured data to version 2.1.8 and added the canonical listing references.
• Added canonical and social preview metadata for PixelArt and added its URL to the sitemap.

Compatibility and format

• Both applications report version 2.1.8.
• No PIX2 syntax, parsing, serialization, import, export or artwork behavior changed. PIX2 remains version 1.1.

Verification

• node tests/run-all.cjs --syntax — passed (35 production JavaScript files).
• node tests/run-all.cjs — passed (20 Node suites).
• node tests/benchmark-performance.js — passed all performance gates.
• node tests/run-all.cjs --browser — passed all 3 browser suites in Chrome for Studio and PixelArt.
• git diff --check — passed.
• GitHub Actions tag workflow — passed, and the stable v2.1.8 GitHub release was published.
• GitHub Pages deployment from main — passed; live Studio and PixelArt pages returned HTTP 200 with the new metadata.

Limitations

• Directory badges link to the listings but cannot ensure that external sites provide followed inbound links or improve search rankings.
• Google does not use the meta keywords tag for ranking; this release removes it rather than maintaining a keyword list.
