/*
 * DRC Rewards — customer portal design system.
 *
 * Visual direction mirrors the internal Nexus UI (deep-navy surfaces +
 * vibrant electric-blue primary) but is a self-contained, customer-facing
 * stylesheet. This is a separate Django project from Nexus, so we mirror the
 * design *tokens* rather than importing Nexus's static files.
 *
 * Theming: all colors are CSS custom properties. The default (:root) theme is
 * DARK. A user toggle flips :root[data-theme="light"] for a light theme. The
 * same token names carry both themes, so every rc- component themes for free.
 *
 * Conventions:
 *   - Every component class is prefixed `rc-` and is token-driven.
 *   - 4px spacing base; radius 4/6/10; type scale 12-24px.
