/**
 * Next Archive Filters (1.2.0) — News archive filter bar.
 *
 * Two labelled rows (Country, Category). Each row is as wide as the content column: when the buttons fit they
 * stretch to fill the whole width; when they do not (phone, tablet, laptop, long category names) the row scrolls
 * sideways with a fade on the edge that has more, plus small arrow buttons on devices with a mouse.
 * Colours come from the theme tokens, exactly like the Latest News block, so dark mode works without extra rules.
 * Override from the theme: .naf-bar { --naf-accent: #ffcf33; --naf-text: #222; --naf-on-accent: #000; }
