/* ============================================================
   Ongoing Support and Enhancement service detail page styles.
   Source: /docs/mockups/support.html.

   Seventh and final service detail page. Patterns shared with
   earlier service pages live in components/:
     - components/svc-hero.css           (hero + what-card)
     - components/svc-hero-label.css     (icon + label identifier)
     - components/cred-strip.css         (credibility strip — now
                                          a fixed sitewide component)
     - components/use-cases.css          (use-case grid)
     - components/related-services.css   (2-up rail)

   What stays page-specific:
   - .models-section + .model-card +
     .models-callout                 3 engagement-model cards
                                     (retainer / on-demand / fixed-
                                     scope) with alternating accent,
                                     plus a "no minimums" callout.
   - .cadence-section + .cadence-step  4-step ongoing-relationship
                                     rhythm. Floating numeric chip
                                     instead of a "Step 1" eyebrow.
   - .case-section + .case-grid +
     .case-timeline                  Long-arc 6-step timeline case
                                     study (per design-system
                                     "long-arc timeline" pattern).
                                     Distinct from the shared 3-stat
                                     .cs-card.
   - .faq-section + .faq-item        Bordered-card + (+/−) accordion
                                     (matches Implementation,
                                     Integrations, Data Migration,
                                     Strategy).

   The big-number .cred-strip-tenure / .cred-tenure-num variant that
   used to extend the shared cred-strip was retired when the strip
   became a fixed sitewide three-Zoho-badge component.
