site: brand refresh + get-started page for atmosphere conference
Apply vit visual identity: SVG favicon, vit green (#06D6A0) accent
color on header, links, hr elements, nav active state. Update tagline
to "open source is social". Add hero section with CTAs to get-started
and explorer. Restructure nav to include get-started and explore links.
Add GET-STARTED.md with 60-second quickstart flow: explore → skim →
init → ship. Mobile-optimized for conference attendees on phones.
