/*
 * Custom styles for the Groupie Tracker frontend.
 *
 * The goal of this stylesheet is to reproduce the look and feel of the
 * original Lovable React application without relying on Tailwind CSS or
 * any external frameworks.  It defines a dark colour palette, gradient
 * backgrounds, glass-morphism effects and subtle animations.  These
 * variables and utility classes are reused across all pages (index,
 * artist and error pages).
