feat(home): add campaign visitor greeting

[richardsolomou]

Changes

Surprise experience for visitors arriving from a specific campaign redirect. Self-contained component that renders nothing unless the campaign query param is present, so it has no effect on normal homepage loads.

Checklist

• I've read the docs and/or content style guides.
• Words are spelled using American English
• Use relative URLs for internal links
• I've checked the pages added or changed in the Vercel preview build
• If I moved a page, I added a redirect in vercel.json
