/* TLO Lease Scanner — Phase 2 frontend
   Design language: a lease is a physical document under a lawyer's red pen.
   Findings are rendered as flag tabs sticking out of the document's edge,
   color-coded by severity. Paper, ink, and a genuine flag-red, used only
   where a flag actually is one — not as decoration. */
