/* Forecast dBZ — the document pages.
 *
 * This is weather.city's highway-signage system, shared unchanged with Forecast
 * Eagle so the three sites read as one network: MUTCD guide-sign green #04663d,
 * motorist-services blue #0a5ca8, warm paper ground #e6e2da, and Overpass — the
 * open, metric-compatible cut of FHWA Highway Gothic, which is the actual
 * Interstate signage face.
 *
 * Forecast Eagle's own note within that system is the Interstate route shield.
 * Forecast dBZ's is **the reflectivity scale itself** — the green-yellow-red
 * ramp every American has been reading off a television since childhood. It is
 * already a piece of signage: a legend, meant to be read at a glance, with hard
 * class edges and no ambiguity about which end is worse. So the site's mark is
 * its own colour bar, and the highway motif and the radar identity end up being
 * one thing rather than two competing ones.
 *
 * The document is light paper throughout. Radar sits in a dark inset panel, the
 * same way weather.city frames its national outlook figures and for the same
 * reason: reflectivity needs a dark ground, the surrounding page does not.
 *
 * The viewer at /radar has its own stylesheet (forecastdbz.css). That page is an
 * instrument, not a document — full-bleed, no scroll, theme-following chrome —
 * and trying to serve both from one file would compromise each.
