Summary

• Refresh the GitHub Pages palette and typography with the LOLBAS-inspired slate and cyan colors.
• Add canonical, Open Graph, and Twitter metadata plus a minimal social preview image.
• Correct Yared Henriquez's name.
• Refine the embedded dashboard: content-sized Decrypter and Audit tables, clearer connection status, compact notifications, and a calm disabled-module state.

Verification

• git diff --cached --check passed before commit.
• Built the dashboard and visually checked the local preview at 127.0.0.1:8081 with gated modules disabled.
