/* ==========================================================================
   3D Zebra stylesheet
   Plain CSS on purpose: no build step, nothing to install, nothing to break.

   Colors come straight from the brand book (October 2021):
     primary   dark blue #023047, white, greys #D1D1D1 / #A3A3A3
     secondary sky #8ECAE6, teal #219DBC, amber #FFB703, orange #FB8600

   THEMING: every color used below is a semantic token defined in the two
   blocks that follow - light values in :root, dark overrides in the
   prefers-color-scheme media query. The site follows the visitor's OS
   setting automatically; there is no JavaScript involved. Dark mode is the
   brand book's other canonical treatment: white text on the dark blue.
   To restyle anything, change tokens here - never hardcode colors in rules.
   ========================================================================== */
