   • Every element tagged [data-reveal] starts invisible.
   • reveal.js adds .revealed when element enters viewport.
   • .section-tag / .section-title / .section-sub / .accent-line
     are automatically handled via JS without needing data-reveal.
   • Page-transition overlay (#page-curtain) slides away on enter.
