/* The storybook homepage — one continuous scroll styled as a single unrolling
   parchment letter. Ported from "Tap-A-Post Storybook Site v2.dc.html"; the
   prototype's inline styles are the pixel source of truth and are transcribed
   here as classes. Values are not rounded or "tidied".

   Scroll-driven pieces (flap, letter rise, name wipe, story fan, treasure
   trail) are set from static/js/storybook.js. Every one has a static end-state
   below so the page is complete with JS off or reduced motion on. */
