/*
 * Bidirection Docs — the stylesheet.
 *
 * The console's own system, retuned for reading: Archivo for prose, IBM Plex
 * Mono wherever the page names something that exists on screen (a nav path, a
 * control, a DNS value). That split is the point — these articles are about
 * driving an interface, so interface words wear the interface's typeface and
 * prose stays prose.
 *
 * Colour is deliberately restrained: ink on warm paper carries the page, one
 * violet accent marks what you can act on, and the two PRODUCT colours are
 * reserved for the Sales/Support badges, where they carry information rather
 * than decoration. The numbered step spine is the one place the design raises
 * its voice, because a procedure's structure IS its content.
