/* ==========================================================================
   FINICHE — MEASURED VS MODELLED
   One visual grammar for data honesty, built on the styles.css tokens:
     observed facts   solid type, solid borders (price, BSR, reviews, timestamps)
     estimates        lavender "model ink", dashed frame, an "Estimate" legend tag
                      sitting on the frame, and a ≈ before every modelled number
     unknown          a plain dash, no styling at all
   Dashed lines already mean "not measured" elsewhere (hm-untracked), so they are reused here.
   CSP-safe: no inline styles; the popover is positioned through CSSOM only.
