/* =============================================================================
   PRODUCTS — page-specific sections
   =============================================================================
   Requires ax-system.css (loaded first): tokens, type scale, buttons, section
   shell, hero, CTA, header/footer, motion. This file styles ONLY this page's
   sections, reusing the shared tokens and editorial registers so Products reads
   as a natural continuation of Home, Services, Industries and About.

   NOT a SaaS catalog — no cards, mockups, feature grids, metrics or tabs.
   Page-unique registers:
     prd-row        · the product editorial spread (Section 3 — the centerpiece)
     prd-principle  · the four design principles, inline weighty set (Section 4)
     prd-shaped     · who shaped them, navy-tick statement list (Section 5)
     prd-cycle      · the evolution loop, key → statement (Section 6)
