/* ===========================================================================
   AI Services platform showcase  (homepage, directly under the top hero)
   Prefix: .aix-   Behavior: js/ai-showcase.js

   Bridges two design systems:
     - bravuramarketing.com : navy #171c2d, cream #f1eee3, orange #e37239,
                              blue #209bd9, Montserrat
     - ai.bravuramarketing.com : oversized condensed uppercase display,
                              diamond bullets, blueprint linework, stat row,
                              pill CTAs with arrows
   The AI site is light-on-warm; this section inverts it to the parent site's
   navy so it reads as bravuramarketing.com while speaking the AI site's
   visual language. Navy also gives the section a hard edge against the tan
   hero above and the cream section below.
