/**
 * Upcoming Events Mosaic (ACF) – Premium image grid section
 * BEM: .uem, .uem-tile. CSS variables for colors, gap, radius.
 * Preset A: 5-tile asymmetric layout (screenshot). Preset B/C: alternate grids.
 *
 * Preset A tile roles:
 *   wrap--1: grid 1/1, small top-left (~1.1:1). wrap--2: grid 2/1, wide top-middle (~1.5:1).
 *   wrap--3: grid 3/1 span 2 rows, tall right (~1:2). wrap--4: grid 1-3/2, wide bottom-left (~2.5:1).
 *   wrap--5: grid 2/2, small bottom-middle, overlay tile (centered card).
 * Overlay on tile 5 = design highlight; overlay-inner shown on hover/focus (desktop) or always (≤768px).
 * Hover: overlay bg 0→0.28, overlay-inner fade+slide; non-overlay tiles get gradient + title on hover.
 * prefers-reduced-motion: no transform/scale; :focus-visible for keyboard.
