/* AI NetRiva — site styles.
   Extracted from the approved design so every page shares one cached stylesheet
   instead of repeating an inline <style> block per page. The token set, type
   scale and component rules below are the design's; the additions are the
   components the extra pages need (pricing table, prose, changelog, tables).

   Deliberately light-only. The design commits to a light page with one dark
   band; bolting on a dark theme would diverge from what was approved. */
