/* ============================================================
   Alfred AI — deck.css
   Shared 16:9 slide-layout library for on-brand presentation decks.
   Authored at a 1280×720 design size; pairs with deck-stage.js (runtime)
   and ds-base.js (loads styles.css tokens + the component bundle).

   A deck is a sequence of <section> slides inside <deck-stage>. Each slide
   is: <section data-label="…"><div class="frame BG"> … </div></section>
   where BG is one of: bg-cover · bg-white · bg-canvas · bg-ink · bg-grad.
   Everything is driven by design-system CSS custom properties — including the
   brand gradient (--gradient-brand); only the soft radial glows use raw rgba.

   Light context only (no [data-theme="dark"]): headlines = Clash Display
   (--font-display), body = Satoshi (--font-sans).
