* Render pipeline (#ref: AGENTS.md Phase 1). Orchestrates slide

*
* - prepare: tear down previous renderer, reset transform, update
*   counter / live region / caption / long description / nav buttons
* - load: either invoke the renderer registry (non-image) or the
*   image loader (image)
* - compose: attach the loaded element into the slot
* - display: commit post-mount state (placeholder fade, transform,
*   slideLoad event)
*
* The four stages are internal; consumers call `renderSlide(ctx)`.
