/**
 * PM Kalkulatory Ogrodzeń - style frontendu.
 *
 * Przeniesione 1:1 z zaakceptowanego prototypu Designera
 * (Designer/produkty-metalowe/kalkulator-ogrodzen/redesign/index.html),
 * bez bloku "podgląd standalone" (body / .pmko-demo-page).
 *
 * Tokeny brandu z crawla produkty-metalowe.pl (Astra + Elementor):
 * - primary #046bd2, hover #045cb4, interactive #2a77b5
 * - akcent pomarańczowy #f45c25 (ceny/wyróżnienia w sklepie)
 * - nagłówki #1e293b, tekst #334155, tło sekcji #F0F5FA, ramki #D1D5DB
 * - Manrope (nagłówki 600-800), Open Sans (tekst), przyciski radius 4px
 *
 * Wszystkie klasy z prefiksem .pmko- (osadzanie w cudzym motywie WP),
 * zero resetów globalnych. Google Fonts NIE są enqueue'owane - motyw
 * sklepu już je ładuje, fallbacki systemowe w tokenach wystarczą.
