/* Shared Winnow-branded reveal.js theme for both decks (technical + business).
   reveal.css ships layout only; colours, type, and slide components live here so
   the decks match the docs palette (dark #11161d, accent #2f6feb). Linked after
   reveal/reveal.css from each deck so it overrides reveal's bare defaults. */
