/* ===========================================================
Deck framework — DO NOT EDIT the rules in this <style> block.
Edit only inside the second <style> block below (per-deck
styles) and inside <section class="slide"> bodies.
Centering uses the bulletproof pattern:
position: absolute; top: 50%; left: 50%;
transform: translate(-50%, -50%) scale(--deck-scale);
JS only updates the CSS variable. No grid, no flex
centering, no transform-origin tricks. This works inside
the OD viewer's nested transform wrapper at any zoom.
