/* Story campaign chrome: runner bar, chapter card, cutscene, encounter frame, chapter
   complete, and the campaign entry points on the Library / world page / title.
   Tokens only (see style.css and storybook.css); shared pieces are the .sb-* components.
   The diorama and stage styles live in story-stage.css; the voyage hub lives in voyage.css.
   Look: a Saturday-morning cartoon. Title cards over live scene art, sticker buttons, postcards.
   Rules for everything below: nothing important waits on an animation (buttons are visible and
   clickable from the first frame), and html.reduced-motion keeps every beat but drops the motion. */
