/* whois.ip-db.com — a record viewer dressed for the front page.

   Two surfaces. The "band" (header, hero, result head, overlays) carries the
   globe canvas: a night sky in the dark theme, a pale morning one in the
   light theme, with --band-* tokens for everything drawn on it. globe.js
   reads the resolved `color-scheme` and switches its palette to match.
   Everything below the band is the record itself — tabular, quiet, and
   themed light or dark by the same tokens. Colour outside the band is
   reserved for severity and for the three kinds of infrastructure on the map
   (web, DNS, mail); nothing below hard-codes a colour a token could carry. */
