/*
 * Design system on top of Bootstrap 5. Still restrained - a business tool,
 * not a marketing page - but with a deliberate color scheme instead of raw
 * Bootstrap defaults, so:
 *  - there is exactly one "brand" color, used consistently for every
 *    forward/primary action (buttons, the active step in the rail, links,
 *    focus rings) and for nothing else - color only ever means "this is
 *    the next thing to do" or "this is a link";
 *  - the Schritt-4 chart's bar color (see attributes.js) IS this brand
 *    color, so the one chart in the app doesn't clash with the UI around it;
 *  - "done" steps get their own green, "back"/secondary actions stay
 *    neutral gray - color is never the only signal (labels/icons carry the
 *    same information), it just reinforces it.
 *
 * Bootstrap's shipped CSS bakes literal hex values into each component
 * class (e.g. .btn-primary sets its own --bs-btn-bg locally), so a single
 * `:root { --bs-primary: ... }` override does not recolor buttons on its
 * own - each component's own CSS variables are overridden below instead.
