/*
** Kivvi site-wide loading indicator
**
** Two indicators share this file:
**   #kivvi-loader-bar     - thin top progress bar, background requests, never blocks input
**   #kivvi-loader-overlay - light scrim + spinner, blocking actions only
**
** The spinner is drawn in CSS, not loaded as an image: nothing to preload, nothing to 404, sharp at
** any size and any pixel density, and it can be paused for prefers-reduced-motion.
