/* ==========================================================================
   Partial Truths carousel — an auto-rotating viewer for the "Partial Truths"
   card series. Built to sit inside pages using assets/style-reference.css:
   it reuses that file's custom properties (--navy, --red, --band, --rule,
   --ink, --muted, --bg-soft) instead of defining its own palette, so it
   inherits whichever theme the page already uses. Loaded only on the page(s)
   that include the carousel — not merged into style-reference.css itself,
   so this addition stays easy to review or remove on its own.
