   Integrations service detail page styles.
   Source: /docs/mockups/integrations.html.

   Fourth of seven service detail pages. Patterns shared with
   earlier service pages live in components/:
     - components/svc-hero.css           (hero + what-card)
     - components/cred-strip.css         (credibility strip)
     - components/use-cases.css          (use case grid)
     - components/svc-process.css        (process strip)
     - components/case-study.css         (3-stat case study)
     - components/related-services.css   (lifted on this page —
                                          2-up rail; second use
                                          after Implementation)

   What stays page-specific:
   - .arch-section + .arch-diagram   Hub-and-spoke architecture
                                     diagram on tinted-light with
                                     light-gray topo callback.
                                     Inline SVG is a working
                                     concept; the .arch-diagram
                                     container can swap in a
                                     single <img> later.
   - .mech-section + .mech-row +
     .mech-callout                   3-row stack of integration
                                     mechanisms (Layer 1/2/3) with
                                     alternating accent on the
                                     left border, plus a
                                     "combine layers" callout.
   - .beyond-section + .beyond-card  2-col layout; narrative on
                                     the left and three "more
                                     than just syncing" cards on
                                     the right.
   - .faq-section + .faq-item        Implementation's bordered-
                                     card + (+/−) accordion.
                                     Divergent from Creator/
                                     Portals' borderless-row +
                                     chevron treatment. Hold both
                                     until reconciliation.
