/*
 * Filter Sidebar — lightweight editorial skin over WooCommerce Product Filters.
 *
 * WooCommerce owns the markup + behaviour (Interactivity API). This file only
 * re-skins it: no gray boxes, hairline dividers, brand checkboxes, a modern
 * range slider, muted counts. Rail is a 260px sticky column on desktop.
 *
 * Targets real WC classes (inspected from rendered DOM):
 *   .wc-block-product-filter-checkbox-list__{items,item,label,input,count,text}
 *   .wc-block-product-filter-price-slider__{content,range,left,right}
 *   .wc-block-product-filter-removable-chips__{item,label,remove}
 *
 * Tokens read: semantic.color.{text,brand,border,surface,input,button},
 *   semantic.radius.badge, semantic.typography.{body,display}, space.*.
