   styles/organogram-ecc.css

   Extends styles/organogram.css with two additions:
     1. An immersive fleet.jpg background + premium glass / 3D cards for the
        district picker.  Everything here is scoped under `.og-overlay.has-fleet`,
        so when that class is absent the original picker styling is unchanged.
     2. A pan-and-zoom image viewer (`.ogi-*`) used for image-based organograms
        such as the Emergency Communication Centre (ECC).

   Loads AFTER organogram.css, so the design tokens declared there
   (--og-navy, --og-blue, --og-gold, --og-teal, --og-ease, --og-dur …)
   are available to this file.
