Remove hero image from blog page

[Copilot]

Removes the standalone hero image section from the blog-with-session page.

Changes

• Removed hero image section: Eliminated the <section class="hero-image"> containing the Unsplash image (lines 117-125)
• Cleaned up resources: Removed heroImage variable, preload link, and unused preconnect to images.unsplash.com

The page now displays only the Showcase component for the hero section.

Before/After

Before:

<Showcase heading="Astro Blog" text="A simple blog built with Astro" showExtra={false} />

<section class="hero-image" style="margin-top: -2rem;">
  <img 
    src={heroImage}
    alt="Astro Blog Hero"
    fetchpriority="high"
    style="width: 100%; max-height: 400px; object-fit: cover;"
  />
</section>

After:

<Showcase heading="Astro Blog" text="A simple blog built with Astro" showExtra={false} />

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• api.trafficbox.com
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node /home/REDACTED/work/astro-test/astro-test/node_modules/.bin/astro dev (dns block)
• dl.deno.land
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node /home/REDACTED/work/astro-test/astro-test/node_modules/.bin/astro dev (dns block)
• jsonplaceholder.typicode.com
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node /home/REDACTED/work/astro-test/astro-test/node_modules/.bin/astro dev (dns block)
• netlifind.netlify.app
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node /home/REDACTED/work/astro-test/astro-test/node_modules/.bin/astro dev (dns block)

  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node /home/REDACTED/work/astro-test/astro-test/node_modules/.bin/astro dev (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
