/**
 * Brand / Sponsor widget.
 *
 * Scoped to `.goxom-br`, which only this widget outputs. The Style tab writes
 * custom properties on the root, and the tile variants below only swap them.
 *
 * The marquee is pure CSS: two identical groups slide left by one group's
 * width plus the gap and loop. The script only adds copies on very wide
 * screens and turns "pixels per second" into --br-dur; without it the row
 * still runs at a sensible default.
