/* Page-level CSS for the marketing site. Everything here was the inline
   <style> block of the static snapshot's index.html, moved into a real
   stylesheet now that there is a server to serve it.

   It defines only page furniture — the plate, headings, CTA, card, well. Every
   value it reaches for is a token from tokens/; nothing is hard-coded, so a
   token change still moves the whole site. Component surfaces (knobs, panels,
