   AISHTMLNEWDESIGN-496 — visual direction: PURE SEQUENCE

   In rummy a pure sequence is the run you must declare before any other
   meld counts. That is the shape of this case study — compliance first,
   then security, then engagement, then scale — so the page reads as a
   hand laid out in order: graphite ink for the two decision bands,
   card-stock ivory between them, one card-red mark for rank chips and
   rules, and no ornament beyond that.

   SHARED COMPONENTS: the CTA button and the enquiry modal are the house
   components cloned from /our-values in AISHTMLNEWDESIGN-492 (jade fill;
   overlay scrolls, box never does). They are reused verbatim rather than
   re-invented, so every enquiry surface on the site presents identically.

   ISOLATION CONTRACT: every selector below begins with
   #page-case-study-cardnation-rummy-multiplayer-platform-case-study.
   No bare element selectors, no body/html rules (the document reset is
   owned by ais-layout.css — frontend-design skill §33), nothing touching
   #ais-header / #ais-footer.

   MOTION (rule 26): the only transitions are hover / focus on
   interactive elements. No keyframes, no infinite animation, no
   scroll-driven effects of any kind.
