/* html-ppt :: runtime.js
|
|
* Keyboard-driven deck runtime. Zero dependencies.
|
|
*
|
|
* Features:
|
|
* ← → / space / PgUp PgDn / Home End navigation
|
|
* F fullscreen
|
|
* S presenter mode (opens a NEW WINDOW with current/next slide preview + notes + timer)
|
|
* The original window stays as audience view, synced via BroadcastChannel.
|
|
* Slide previews use CSS transform:scale() at design resolution for pixel-perfect layout.
|
|
* N quick notes overlay (bottom drawer)
|
|
* O slide overview grid
|
|
* T cycle themes (reads data-themes on <html> or <body>)
|
|
* A cycle demo animation on current slide
|
|
* URL hash #/N deep-link to slide N (1-based)
|
|
* Progress bar auto-managed
