/* Centred by layout, not by transform.
   The previous `left: 50%; transform: translate(-50%, …)` broke as soon as GSAP
   animated `y`: GSAP takes ownership of `transform` and resolves the -50% into a
   fixed pixel offset measured from the element's width at that instant. Every
   later message with a different length kept that stale offset and sat off-centre
   by half the width difference. Pinning left/right and letting auto margins do
   the centring leaves `transform` entirely to GSAP. */
