   Deep-link fade-in (two-class state machine)

   1. Inline <script> in <head> adds .deeplink-fade BEFORE first paint.
      The deck renders invisible from frame 0 — no flash.
   2. After deck.js positions the scroll, it adds .deeplink-ready on the
      next animation frame. The opacity transitions from 0 → 1 smoothly.
   3. Both classes are stripped once the transition finishes, so subsequent
      :target changes (sidebar clicks, scroll-driven hash updates) leave
     the deck untouched.
