/* Theme: every colour, font and size the deck uses.
   Change the look here. Layout and slide mechanics live in deck.css.
   Sizes are canvas pixels: the slide is a 1600 × 900 canvas scaled to fit the window,
   so 64px here is 64px on a 1600-wide slide, like in Keynote or Figma.

   Colours come from the old leomuzicarvalho.github.io: the dark matrix hero, the
   #74e3f2 link cyan, and the mint / cyan / sky hexagons of the old logo. */
