/**
 * XC Product Filter Pro — Frontend Styles (v1.0.2)
 * Mode: Inherit Theme (default) — colors cascade from the active theme.
 * Layout: unified panel design inspired by FilterEverything Pro / modern Laravel
 *         e-commerce templates. No horizontal dividers between filter groups —
 *         visual separation comes from spacing, weighted headers, and an optional
 *         soft card wrapper.
 * Fully responsive: 320px → 2560px+
