   DECK BASE  —  layout engine shared by every slide, theme-agnostic.
   ----------------------------------------------------------------------------
   Provides: reset, the 12-column Bauhaus grid, the color-BLOCK primitives,
   list/agenda structures, kickers, boxed labels, and the typographic scale.
   Colors + fonts come from the active theme (.theme-01 / .theme-02) via tokens.
   Built for reveal.js (each slide is a <section>), but the utility classes work
   in any HTML deck.
