/* Feature 042 — the shared story presentation: badge, strip, segments, section heads, toolbars, empty and loading
   states, run facts, fields card, status chip, prompts tab and overview card, for every reusable demo experience.
   Tokens come from brand.css only; the experience stylesheets keep their own views and never override these
   blocks. The token map is documented in docs/demo-story-engine.html and follows the ArchitectNow Style Guide:
   colour (pp. 10–16), type (pp. 18–22), spacing on 4 (p. 25), radii 4/8/12/16 (p. 26), buttons and focus (pp.
   29–30), cards (p. 31), validation (p. 34) and the section label, numerals and proof bar (p. 38). */
