/* Story pages — shared kit of the redesigned Plateforme, Par initiative (hub and four pages), Contact
   and Qui sommes-nous, in the family of /flowy-ai/ and /design/home-souveraine/.
   Final states are the defaults (no JavaScript, reduced motion). `.st.is-live` (motion.tsx) rewinds
   them: `[data-at]:not(.on)` is the state before a threshold, `--p` the scroll progress of the closest
   `[data-progress]` block. `.st.is-pinned` (large screens, motion allowed) enables pinned stages.
   Not-yet-reached items are dimmed by colour (`.st-dim`-like rules), never by opacity, so text keeps a 4.5:1 contrast.
   Rewound states only use transform, opacity or colour: nothing changes the layout (no layout shift while scrolling).
   The luminous line is the common thread: cursor, form structure, workflow connection, data flow,
   perimeter or activity signal, depending on the scene. *//* Arial sized like SfSans (measured: 103.8 % normal, 100.6 % bold): no reflow when the web font swaps in.
