/* ==========================================================================
   Focal IT Consulting: scroll stories (stories/*.html)
   Builds on styles.css and uses its Palette v1 tokens only.

   How it works
   - Without JavaScript, or with reduced motion, every scene is a normal
     block: text, then its figure in its finished state, in one centred
     column.
   - With motion allowed, the head script adds .story-anim to <html>.
     story.js then sets --p (0 to 1) on each figure as the reader scrolls,
     and every moving part below reads --p. Only opacity and transform
     change.
   - From 1100px wide the figures share one pinned panel beside the text.
     Only one figure shows at a time: the old one fades out, then the new
     one fades in. Inactive scene text is muted (colour, not opacity).
   - Sentence case throughout: nothing here sets text-transform.
   ========================================================================== */
