/*
 * Partner logos that scroll along ([oak_partners]).
 * - Two rows drift in opposite directions; each row is its list twice, and
 *   both copies slide one list-width left, so the loop has no seam.
 * - Tiles share one size and the leaf curve on their bottom-right corner;
 *   logos are sized by area in partners.php so they look the same weight.
 * - Hover holds a row; the pause button holds both. Reduced motion: a still grid.
