/* ============================================================
   AI SERVICES  —  /ai-services/ and /ai-services/{slug}/
   ------------------------------------------------------------
   Loaded after services.css, which supplies .section, .sec-head, .title,
   .faq-*, .cta and the ink-panel treatment. Only what is specific to this
   section lives here.

   The one idea: these pages are read by people who are nervous about AI, so
   the page is ordered reassurance-first. The hero carries a fixed "how we
   start" card instead of a decorative image, and the ink panel is spent on the
   "where this goes wrong" section rather than on a sales block. Everything is
   in tokens so both light sections and the ink panel stay correct.
