 * Customize the CSS variables for your theme (or switch to the dark mode shown below).

 * IMPORTANT: All font sizes use pt (points) for predictable sizing.
 * Base text is intentionally small (16pt) to fit content-heavy slides.
 * Use .text-lg, .text-xl, etc. classes when slides have less content.
