/*!
 * RFK Filters — styles
 * --------------------------------------------------
 * Black + gold tokens match the rest of the site (kings.css).
 * Desktop: filters render as a horizontal bar above the grid.
 * Mobile (<768px): the "Filters" button opens a bottom sheet that slides
 * up over the content with a sticky "Apply (N results)" footer.
 *
 * No external dependencies. No JS-managed inline styles for layout — JS
 * only toggles classes and aria attributes.
