Kadal Deck 0.11 closes its remaining reveal.js compatibility gaps

Kadal Deck, a presentation tool, already imported reveal.js decks closely, but a 0.10.1 audit of 164 features across 27 areas found gaps. In version 0.11, 23 options that previously had no effect now work, including centering, shuffling, fragment and embedded modes, and deck-wide line numbers. Imported decks keep their original look, since reveal's themes ship as a package and its layout classes and keycodes are supported. The deck also emits reveal's events and responds to its postMessage calls, so scripts written for reveal.js can drive it. Maths written for MathJax is carried into KaTeX at build time, with unsupported features such as \require listed in an import report, and the original deck is left untouched. The source format remains different, since a Kadal deck is a single MDX file built with Vite.
