/* Shared Insights ticker (ISD navy). Used on insights/index.html and the home hero strip.
   Item copy lives in insights/ticker.json; run sync-ticker.py after changing it.
   Weekend ticker conventions (Captain 2 Nov 2026): full-bleed, identical passes,
   seamless loop, pause on hover and keyboard focus, no motion when reduced.
   No gap above the Insights strip (Captain 2 Nov 2026): the Reference guides row ends flush on the ticker. */
