/* ==========================================================================
   NeoAI deck pages: one point per screen, scroll-snapped, fits 390x664.
   Load after /type.css. Component reference lives in deck/README.md.
   Rules of the house:
     - every slide heading is a claim
     - mock data is realistic and labelled (.tag.*), never presented as results
     - a slide must fit 390x664 and 1280x720 without scrolling (scripts/check-fit.js)
