v2.3.20

Changed

• CNCF Showcase Conformance Image Effects: Added a glassmorphic wrapper .hero-showcase-wrapper to the main CNCF conformance image on the V2 homepage with hover scale effects (1.03x), brightness filters, a neon cyan shadow glow, and an interactive overlay badge.
• V2 Nav and Index Path Fixes: Resolved broken internal references to videos.md in v2-mkdocs.yml and the strategic dimensions list by permanently updating the compiler to resolve paths to the modularised ./videos/index.md location. Integrated MkDocs Material's navigation.indexes feature so that clicking the top-level "Agentic Video Hub" menu tab links directly to the Overview page (videos/index.md) without sub-navigation redundancy.
