/* ── Loop Pipeline Visualizer ── */

/* COLOR SCHEME → ui/shared/css/design-system.css (single source of truth).
   No raw hex/rgb here: use var(--brand) / var(--accent) / var(--accent-hover) for
   the brand accent, rgba(var(--brand-rgb), a) for any accent opacity, var(--success|
   warning|danger) (or rgba(var(--*-rgb), a)) for status, var(--purple) for the 2nd hue.
   Need a colour that doesn't exist yet? Add a token to the palette in design-system.css
   (the dark :root block AND its body.light-mode twin), then reference it here.
   Re-theming the whole app (e.g. peach → green) is then a one-file edit. */
