/* appteczka.eu — scroll story (agent S). Everything here lives inside .story, plus the .story-pill canvas
   and the landing state of the footer sign (.foot-logo).
   Progressive enhancement:
   - without JS (no html.js) the chapters are plain blocks with a static gradient per scene, panels and
     phones fully visible, the footer sign complete;
   - html.js turns chapters into 250vh scroll rooms with a sticky .pin and hides panels/phones until
     story.js fades them in (through the custom properties --in/--out/--ph-in/--ph-out/--drift);
   - story.js adds html.has-story when it runs; only then is the top arm of the footer sign empty
     (waiting for the capsule). If the canvas is unavailable it adds .story-off and everything shows.
   Panels never use theme tokens: their colours are fixed per data-tone, so they read the same in the
   light and the dark theme of the page. Breakpoint: 900px, the same query as in story.js. */
