/* Spider Solitaire board: a stock indicator and completed-sequences
   counter in a row above ten cascading tableau columns - the same
   overlap-via-negative-margin cascade layout as Klondike/FreeCell,
   just with more (narrower) columns since Spider deals 10 instead of
   7/8. Card faces match Klondike/FreeCell (red suits hollow, black
   suits filled). Like those two, `.spider-card` and `.spider-empty-slot`
   get their height and overlap in JS from the measured column width
   (CardFaces.layoutColumns in card-faces.js), since `aspect-ratio` is
   unreliable on E-Ink browsers. No CSS min-height on the cards:
   `min-height` always wins over a smaller explicit `height`, so on a
   narrow board it silently overrode the computed height and stretched
   every card. (The JS sets min-height on the columns only, so an empty
   column can still be tapped.) */
