   gameManager/MTG/diceRoll.css — ★2026-09-05 THE OPENING ROLL
   (mechanics/diceRoll.js creates every element styled here; index.php has
   no markup for any of it). Fully self-scoped: #rollDiceBtn,
   #diceRollOverlay, #rollWinOverlay, .roll-die, .roll-label,
   .roll-win-dialog and body.roll-phase.

   z-order: the Roll Dice button and the parked dice sit at 7 (with the
   turn controls — above the hand strips (2–4) and the life dice (6), below
   the deck viewer / floating cards at 1000); a die in flight is 1600 (a
   throw happens on an empty table — nothing else is that high then); the
   presentation overlay is 9620 (above the card presentation's 9600, below
   the turn splash 9640 and the dice popup 9700) and the presented die +
   its label ride just above it; the winner dialog is 9630.

   ★2026-09-07 — THE 3D d20
   diceRoll.js's buildD20() writes:

     <div class="roll-die roll-d20 die-c-<color> d20-t-<texture>"
          style="font-size:<die px>">
       <div class="d20-scene">                       perspective
         <div class="d20">                           the rotating body
           <div class="d20-face d20-t-<texture>"      × 20
                style="clip-path:polygon(3 vertices); transform:matrix3d(u,v,n,c)">
             <div class="d20-shade"></div><span class="d20-num">7</span>

   THE TWO SIZES. The geometry is authored once at 100px (D20_BASE) and the
   BODY is scaled by the same matrix that rotates it, so a die is resized by
   font-size alone — which is what lets the presentation's fly() grow it.
   `.d20` therefore pins font-size:100px so the em-based texture gradients
   copied from dice.css below resolve against the AUTHORED size, not the
   painted one; the root's own font-size is left to drive the perspective.

   THE COLOUR comes from dice.css: `.die-c-*` sets --die-base/-hi/-lo/-ink/
   -ink-shadow and nothing else, so putting that class on the root is free.
   The `.die-t-*` classes are NOT reused — they paint a square die body and
   would show through the polyhedron — so the textures are re-cut here as
   `.d20-t-*` overlays on each face.
