/*
 * Homepage solar calculator («Калькулятор сонячних панелей»).
 * Markup: template-parts/solar-calculator.php, behaviour:
 * assets/js/solar-calculator.js. Loaded after autonomy-calculator.css: the
 * section is `.ac.sc`, so the card, scene, pins, cables, appliance chips,
 * dark panel, tabs, buttons, phone dock, tokens and reduced-motion rules all
 * come from there. This file adds what the solar mockup has on top: season
 * crossfade, panel cards with a quantity stepper, station / season pills,
 * the result block and bars.
 *
 * Breakpoints are the autonomy calculator's: ≥1200 desktop, 768–1199 tablet,
 * <768 phone.
