/* ==========================================================================
   HERO — the first band of every page
   ==========================================================================
   The hero article goes in the layout's Hero section (article "Display in:
   Hero"), so #hero is the hook. The article carries only its variant class:

     hero--light   cream band, navy copy. A statement (`hero__frame`) or
                   columns (`hero__intro`: copy | divider | stat rail or card)
     hero--split   Home: headline | divider | copy + buttons, stats row below
     hero--text    dark gradient, white copy

   Decor sits in a first text element `hero-decor`: `.hero-wash` (light
   heroes) or `.hero-blobs` (Home).
   ========================================================================== */
