/* ============================================================
   Implementation service detail page styles.
   Source: /docs/mockups/implementation.html.

   First of seven service detail pages. As later pages landed,
   shared patterns were lifted out of this file into components/:
     - components/cred-strip.css         (Creator)
     - components/use-cases.css          (Creator)
     - components/svc-process.css        (Creator)
     - components/case-study.css         (Creator)
     - components/svc-hero.css           (Portals — hero + what-card)
     - components/related-services.css   (Integrations — 2-up rail)
   Those styles are no longer in this file.

   SHARED CANDIDATES still pending:
   - .faq-section + .faq-item           (Implementation and
                                         Integrations use the
                                         bordered-card + (+/−)
                                         accordion. Creator and
                                         Portals use borderless
                                         rows + chevron. Two pairs;
                                         pick canonical and lift
                                         when one of the four
                                         pages next gets touched.)

   Page-specific (no plans to share):
   - .mvp-section + .mvp-timeline       (MVP staged-rollout visual)

   The .svc-id experiment lifted into components/svc-hero-label.css
   when the icon + label treatment rolled out across all six
   service detail pages.
