/* deck.css: theme for "What Is Left to Write?" (MLL seminar, 1 October 2026).
   v0.1, 28 September 2026. Dark only. Palettes: flyer (default), richter, ink (key P).
   Grey treatments for the crisis slides: canvas (default), horizon (key Y). G jumps to a slide.
   Chart colours are constant across palettes and were checked with the dataviz
   validator on all three grounds: gold #c98500 and blue #3987e5 pass together;
   red #e66767 passes with blue but NOT with gold, so red never shares a chart with gold;
   violet is decoration only (it collapses into blue under protanopia). */
