Description

CSI teams need a dedicated stream for the Microsoft AI Enablement Series without mixing it into Build Days. This adds a README-backed /ai-enablement/ page that works both on GitHub and on the existing Primer-based Pages site.

Changes

• Include all six session summaries, the full dated schedule, original Teams registration links, and the approved series banner.
• Connect the stream to the homepage, shared navigation, route handling, and multi-page build; update contributor guidance for the expanded scope.
• Keep the banner within the reading column and schedule headers left-aligned.

The source email/PDF and personal metadata are excluded. Past scheduled dates remain in the full schedule without implying that registration is still open or recordings are available. Build Days content is unchanged.

Validation

• npm run build passed with Node.js 22.22.1.
• Reviewed all five routes in light and dark modes at 360, 900, and 1440 pixels.
• Verified navigation, deep links, keyboard focus, theme persistence, reduced motion, mobile TOCs, table overflow, and project-relative assets.
• Confirmed all six Teams event links against their session pages.
