Horizontal swipe deck in one HTML file. You get a proven five rule iframe nav script, six CSS tokens mapped from your design system, and eight paste ready slide layouts covering hero, stats, three column, quote, pipeline, and before/after. The workflow forces you to sketch theme rhythm before writing any slides so you don't end up with four light slides in a row putting everyone to sleep. Built for product overviews, pitch decks, and study material when you need something clean that works in an iframe without fighting scrollIntoView bugs. No build step, no framework, just copy the template and fill it.
