/* Base reveal.js styles
 *
 * Copy this file as styles.css for each new presentation.
 * Customize the CSS variables (especially colors) for your theme.
 *
 * 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.
