   kapnova-site.css
   Shared styles for the Kapnova marketing pages. Every rule here was
   byte-identical on all 12 pages, so it lives in one place instead of
   being repeated in each file.

   Each page keeps its own <style> block, loaded after this file, for the
   sections unique to it. Rules whose selectors a page overrides locally
   (responsive grid overrides, for example) deliberately stay in the page
   so the cascade order is unchanged.

   Design tokens are documented in ../styles/kapnova-tokens.css (the
   design-system reference, not served to the browser); the :root block
   below is the copy the live pages actually use.
