> One command installs **36 themes × 20 canvas FX × 31 layouts × 15 full decks + presenter mode**. Every preview above is a live iframe of a real template file rendering inside the deck — no screenshots, no mock-ups.

## 🎤 Presenter Mode (new!)

Press `S` on any deck to pop open a dedicated presenter window with four
draggable, resizable **magnetic cards**: current slide, next slide preview,
speaker script (逐字稿), and timer. Two windows stay in sync via
`BroadcastChannel`.

**Why previews are pixel-perfect:** each card is an `<iframe>` that loads the
same deck HTML with a `?preview=N` query param. The runtime detects this and
renders only slide N with no chrome — so the preview uses the **same CSS,
theme, fonts and viewport** as the audience view. Colors and layout are
guaranteed identical.

**Smooth (no-reload) navigation:** on slide change, the presenter window
sends `postMessage({type:'preview-goto', idx:N})` to each iframe. The iframe
just toggles `.is-active` between slides — **no reload, no flicker**.

**Speaker script rules (3 golden):**
1. **Prompt signals, not lines to read** — bold the keywords, separate
   transition sentences into their own paragraphs
2. **150–300 words per slide** — that's the ~2–3 min/page pace
3. **Write it like you speak** — conversational, not written prose

See [`references/presenter-mode.md`](references/presenter-mode.md) for the
full authoring guide, or copy the ready-made template at
`templates/full-decks/presenter-mode-reveal/` which ships with full 150-300
word speaker scripts on every slide.
