/*
 * AUTOOL Brand Decor 2.0 — "measurement bus" (plans/FLOW-PLAN.md).
 * One svg per page section, drawn by bus.js from the layout's own axes: two guides on the content
 * edges, a crosshair where each section meets them, a ruler beside each section's eyebrow, one signal
 * on the left guide with an outward pulse at every eyebrow, and dot fields stitched across alternate
 * seams. Segments line up section to section, so the page reads as one continuous line.
 * Decorative only: behind the content (host isolates, layer z-index -1), aria-hidden, no pointer events.
