v1.2.0

1.2.0 - 2026-05-06

• Refactored color-mix() usage into named dependent variables so generated colors can still be overridden.
• Split theme palette variables into vitre.light and vitre.dark cascade layers while keeping shared variables in vitre.theme.
• Added explicit spacing between adjacent card-rendered semantic panels, including document sections, articles, asides, and nested section articles.
• Replaced blank kitchen sink media placeholders with local MP3 and MP4 examples, a YouTube iframe embed, and live object/embed examples.
