/* ==========================================================================
   Leap Dynamics — home page
   Kylan Walters, 2026

   Only the home page loads this. It holds the sections that exist nowhere
   else: the hero carousel, the value tiles, the fleet tab panel, the cargo
   rail, the network band and the partner logo walls.

   Everything shared — tokens, header, drawer, footer, typography, buttons —
   lives in css/leap-core.css, which loads first. This file was split out of
   the original css/leap-landing.css when the rest of the site adopted the
   same chrome; structure and layout still follow the Atlas Air homepage, with
   Leap's palette and wordmark.
