Summary

Replaces public/og-image.jpg with the new social share card ("Classified mission starts Oct 30, 2026") and updates the image's alt text.

Why

The old share card no longer matched the current campaign artwork.

Behavior

  • Same URL, filename, MIME type and dimensions (1200×630), so og:image / twitter:image / og:image:width|height|type needed no changes.
  • Re-encoded through sharp (mozjpeg, q88): strips the source EXIF block and cuts the file from 194 KB to 85 KB.
  • ogImageAlt now reads "DevFest.cz 2026 — classified mission starts Oct 30, 2026"; the previous "conference banner" no longer described the card.
  • Social scrapers cache by URL, so Facebook/LinkedIn will keep showing the old image until the page is re-scraped in their debuggers after this ships.

Files

  • public/og-image.jpg
  • src/layouts/BaseLayout.astro

🤖 Generated with Claude Code

Replace the social share card with the new "Classified mission starts
Oct 30, 2026" artwork. The file is re-encoded through sharp (mozjpeg,
q88), which strips the camera/editor EXIF block and cuts the image from
194 KB to 85 KB at the same 1200x630 dimensions.

The og:image / twitter:image meta tags keep the same filename, type and
dimensions, so only the alt text needed updating — "conference banner"
no longer described what the card shows.
