v0.10.0

v0.10.0 - 2026-07-02

• Breaking: Allow setting slide-view, key-control, and follow-active
  attributes when calling the <build-deck> component.
  The default slide-view is still article,
  but the others have been removed by default.

v0.9.1

Use @container rather than @media for determining when slides can be full-height rather than using an aspect-ratio. This allows the slide-deck to be nested inside a page and still provide different views.

• Breaking/Fix: <embed-slide> only overrides the natural dimensions of <iframe> and <video> embeds.
