Priority fixes for mbta.com

Ordered by impact and by how common each practice is among peers.

Priority 1 · Harden
TLS 1.3 negotiated
Observed: The TLS connection negotiated TLSv1.2.
Why it matters: TLS 1.3 removes legacy cipher suites and completes the handshake in fewer round trips, so it is both safer and faster for new connections.
What to do: Enable TLS 1.3 on your CDN or server. Keep TLS 1.2 available for older clients unless you have checked your audience.
85% of Trains & Public Transport peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.

Priority 2 · Enable
XML sitemap discoverable
Observed: No sitemap was listed in robots.txt or found at /sitemap.xml.
What to do: Generate an XML sitemap of canonical URLs, reference it in robots.txt and submit it in Google Search Console.
66% of Trains & Public Transport peers do this.

Priority 3 · Accelerate
Modern image formats in use
Observed: The homepage had 8 images and none used WebP or AVIF.
What to do: Serve WebP or AVIF with a JPEG or PNG fallback, either through an image CDN or by generating both formats at build time.
28% of Trains & Public Transport peers do this.
Guide: AVIF, WebP, JPEG, and PNG: Choose the Right Image Format
