/* =============================================================================
   ShiftHawk — hero chip hover popups
   Self-contained "Swap detail" calendar popups for the three floating hero
   chips (Mirror / Simple / Triple). Prefix: .hcp-
   Tokens come from styles.css (--banana, --lilac, --r-2, --shadow-lg, fonts…).
   The popup card is always a LIGHT "app screen" (dark-on-light) in both themes,
   so we set explicit colors inside the card — never inherit page text color.
