   Layers ON TOP of /_shared/style.css (frozen — never edit it).
   Direction (docs/marketing/research/yourflow-lane.md §Design):
   document-as-artifact. Ledger rules, dot leaders, tabular
   numerals, a signature line, a gold founding stamp. Harbor-blue
   ink (#0E5A8A) on the shared warm paper — operator-grade
   document, not a corporate deck and never a hype page.
