What problem does it solve? Turning a HyperFrames composition into a navigable presentation deck requires a specific JSON island schema, slide writing rules, fragment hold-points, and presenter-mode wiring that are easy to get wrong, and rendering a deck to MP4 silently truncates the output. ## Core Features & Use Cases - Deck authoring contract: Declares slides via a application/hyperframes-slideshow+json island with scene IDs, speaker notes, fragment reveal times, and hotspot-driven branch sequences. - Presenter mode and handoff: Built-in Present button, audience tab sync via BroadcastChannel, editable localStorage-backed speaker notes, and Google Meet/Zoom screen-share guidance. - Source page conversion: Ports existing pages into decks while preserving visual design, media behavior, scroll-driven camera transitions, and interaction fidelity. - Use Case: Convert a startup pitch page into a 10-slide deck with fragment reveals on the problem slide, a hotspot branching into market-sizing math, and presenter notes for a live investor demo. ## Quick Start Ask the assistant to turn your content or existing page into a HyperFrames slideshow deck with slides, speaker notes, and fragment reveals, then confirm when prompted.
