/**
 * `usePresentationEffects`: the `$effect`-based wiring that drives the Svelte
 * viewer's presentation mode from its reactive state. Extracted from
 * `PowerPointViewer.svelte` (mirroring `useViewerEffects`) so the SFC stays thin
 * and this logic is lintable; runs during the component's setup exactly as if
 * inlined, since Svelte 5 effects only require synchronous registration.
 *
 * Two effects:
 *  1. Drive the {@link PresentationController} lifecycle from the fullscreen flag
 *     and current slide: `start()` on enter, `stop()` on exit, `onSlideChange()`
 *     on every in-presentation navigation (resets builds + plays the incoming
 *     slide's transition).
 *  2. Push each element's native-animation state (visibility, CSS animation,
 *     trigger-shape cursor) onto the live stage after every DOM update (slide
 *     change / build advance / auto-advance) and keep the per-slide native
 *     `@keyframes` injected. When not presenting it clears the managed
 *     properties so the windowed / editing canvas never carries animation state.
 *     Structural reveals (chart / SmartArt build, `p:animClr` fill / stroke) are
 *     applied declaratively by the renderers via the element-states context.
 *  3. Route interactive / hover trigger events on the live stage.
 *  4. Arm the current slide's authored `p:transition/@advTm` auto-advance.
