 * --card-sm-*, --card-md-*, --card-lg-* (size tiers)

    font-size: 1.4em;
    line-height: 1;
    text-align: center;
    font-weight: 800;
    /* line-height:1 still reserves the font's full ascender space above the
       rank's cap-height, and the suit SVGs carry a little slack of their own
       inside the viewBox, so a naively centered rank+suit pair sits off the
       card's true center. This margin cancels the difference.
       Measured, not guessed: rank ink from a canvas raster scan of the actual
       glyph, baseline from a zero-height inline probe, suit ink from the root
       svg getBBox() (must be the root -- spade and club put part of their ink
       in a sibling polygon, so measuring only the <path> reads short and
       inflates the bottom gap). At -0.06em the ink midpoint lands within
       ~0.3px of the card center on all four size tiers and on the card-picker
       variants that shrink the suit to 1.2/1.3em. Re-measure the same way if
       the rank or suit font-size changes. */

/* ---------------------------------------------------------------------
   Classic variant (.card-classic)
   ---------------------------------------------------------------------
   Real-card look: a small rank+suit index in the TOP-LEFT corner plus one
   large suit pip in the centre. Markup differs from the base card -- it
   needs a .card-corner wrapper (rank + mini suit) and a .card-pip (large
   centre suit):

     <span class="playing-card red card-classic">
       <span class="card-corner">
         <span class="card-rank">2</span>
         <span class="card-suit">{suit svg}</span>
       </span>
       <span class="card-pip">{suit svg}</span>
     </span>

   Because the identity sits in the small top-left corner, a fan can overlap
   even tighter than the left-index variant while every card stays readable,
   and a fully visible card still reads as a normal playing card.

   Honors --card-width / --card-font; no new sizes. Experimental: previewed
   in the design system only, not wired into any feature.
