/*
 * Core stylesheet for the ChileSAT website.  This file defines
 * typography, layout and colour scheme for the entire site.  The
 * palette takes cues from the Chilean flag—deep blue and a warm red—
 * resulting in a professional yet approachable look.  Sections and
 * cards employ subtle shadows and rounded corners to evoke depth
 * without distraction.  The design is responsive down to mobile
 * sizes using flex and grid layouts where appropriate.
