🐛 Bug: Homepage crashes when calendar (iCal) fetch fails , "Cannot read properties of undefined (reading 'map')

Describe the bug

The homepage can crash at build time or when loading if the Upcoming events data from the external Google Calendar iCal feed is missing or fails to load.

The page uses props.datesInfo.map(...) in the "Upcoming events" section. When the calendar URL is unreachable (network error, Google down, or parse failure), datesInfo is undefined. Calling .map() on it throws:

TypeError: Cannot read properties of undefined (reading 'map')

Steps To Reproduce

1. Go to the homepage source: pages/index.page.tsx.
2. In getStaticProps, temporarily force calendar data to be undefined (e.g. set const datesInfo = undefined; before the return, or point remoteICalUrl to an invalid URL so the fetch fails).
3. Run the dev server (yarn dev or npm run dev) and open http://localhost:3000.
4. See error: the page crashes with "Cannot read properties of undefined (reading 'map')" in the "Upcoming events" block (around line 549: props.datesInfo.map(...)).

Expected Behavior

If the calendar fetch fails or returns no events, the homepage should still load. The "Upcoming events" section should show an empty list (or a short message like "No upcoming events") instead of throwing.

Do you think this work might require an [Architectural Decision Record (ADR)]? (significant or noteworthy)

No

Start in pages/index.page.tsx, especially getStaticProps and the Upcoming events block around line 549. Run the homepage with the calendar data unavailable using yarn dev or npm run dev, then verify the page loads without the map error and presents an empty or explanatory events state.
