/**
 * WRC Partner Logos.
 *
 * Replaces the plain Elementor image grid on the RDI Projects page with a
 * card showcase: equal-height cards, centred logos, filtering, search and a
 * staggered reveal.
 *
 * Colours are the WRC brand set, used sparingly for accents and hover states.
 *
 * Note on !important: the parent theme styles headings, buttons and inputs
 * globally with higher-specificity selectors (and paints all button text
 * white). Everything here is scoped to .wrc-partners so nothing else moves.
