Presenting without sharing my screen
summary
Builds slide decks as MDX + Gatsby pages hosted on the web and uses socket.io + redux-socket.io to push a single presenter index so every attendee loads a crisp local copy instead of streaming video. Shows Lottie confetti, editable code blocks, themes, live Q&A and polls, and a presenter-auth check (socket id + password) and an “unfollow” button. Reports audio ~17 MB/hr, SD video ~0.7 GB/hr, HD ~2.5 GB/hr and claims deck+audio ~90 MB/hr. Adds experimental pose‑net gestures for next/prev; works in small tests but is marked experimental.
