/*
 * ds.css — thecredit design system · "The Ascent"
 *
 * Concept: your credit score is your ALTITUDE. The app is a climb from the
 * valley (300) to the summit (850). Cartographic, expedition-grade, earthy —
 * topographic contour lines, altimeter readouts, a trail of waypoints.
 *
 * Token-driven, theme-aware (light parchment / dark night-mountain), and built
 * on the native system font stack (no webfont, no CDN) so it carries straight
 * into the future mobile app and renders identically in a webview.
