/* SBC Ally Logos — Frontend styles (v1.1.0)
 *
 * Two presentation modes:
 *   .sbc-al-mode-mobile  → paginated crawl (default before JS runs)
 *   .sbc-al-mode-desktop → static centered grid
 *
 * The block emits BOTH sets of markup. JS adds the right mode class to the
 * block root based on viewport vs. the configurable breakpoint, then toggles
 * on resize. Before JS runs, mobile mode is the safer default for small
 * screens where most users see content first.
 *
 * Per-instance variables (set via inline style on the root):
 *   --sbc-al-max-width  desktop container max width (px)
 *   --sbc-al-cols       desktop logos-per-row
 *   --sbc-al-row-gap    desktop row gap (px)
 *   --sbc-al-bp         breakpoint (px) — informational only
