// astro.config.mjs
astlide({
  plugins: [myPlugin],
  slideDecorators: ["./src/components/DeckFooter.astro"],
  toolbar: ["prev", "counter", "next", "draw", "camera"],
  font: "https://fonts.googleapis.com/css2?family=…",
  drawings: { persist: true },
});

Plugins add themes, layouts, transitions, Shiki languages and decorators
Slide decorators render on every slide — the footer below is one, reading getDeckContext(Astro)
Toolbar: pick and order its buttons
Fonts: Inter by default, or your own
Drawings can be kept across reloads
