/* Obavy a motivace – slides for a projector (obavy_motivace.php, 00-materials/2026_10_26-obvay_motivace.md).
   Builds on style.css (colours, brand, buttons). A slide is a 16:9 card whose type scales with
   its width (container units), so it reads the same on a laptop and a projector. Narrow screens
   and pages without JavaScript show the slides one under another. */
