/*!
 * PMA Shop Filters v3 — minimal / architectural filter UI.
 * Light + dark themes, RTL/LTR aware, no gradients, no heavy shadows.
 * Author: Saeed Salimi Shad <saeedsalimi.ir@gmail.com>
 *
 * SPECIFICITY NOTE
 * Nearly every rule below is written as `.pma-sf .pma-sf__thing` rather than
 * `.pma-sf__thing`. That is deliberate. This panel is dropped into a sidebar
 * owned by a commercial theme (Woodmart and friends) whose stylesheets target
 * `.widget button`, `.widget ul li`, `.widget input` and so on with two-class
 * specificity. A single-class rule loses that fight, and the symptoms are
 * exactly the ones this panel used to show: theme grey bands on headings,
 * missing checkbox ticks, doubled chevrons. Two classes wins cleanly without
 * a single !important.
 */

/* =====================================================================
 * 1. Design tokens
 *
 * Every value here is a fallback. The real values arrive as inline custom
 * properties from PHP (PMA_SF_Helpers::css_vars), which is what lets the
 * shop owner repaint the whole panel from the settings screen without a
 * hard-coded colour anywhere in this file.
