/* ---------- OC-01a · the pilot funnel ----------
   Built in HTML/CSS, not SVG. An SVG with a fixed viewBox scales its height and its type
   with its width, so a full-bleed chart would grow absurdly tall on desktop and render
   unreadable 4px labels on a phone. Percentage-width divs stretch to any container while
   the text stays at real font sizes. Idiom (bar pair + measure) from OC-D88 in
   deck/organizing-our-thoughts.html.

   THE DEFAULT IS THE BUILT STATE: bars sit at full width and everything is opaque, so the
   figure is correct with JS off, under reduced motion, and in print. main.js animates FROM
   a collapsed state, never to one.

   --all / --few are set on the figure in the markup and are the single source of truth:
