/*
 * IBM Plex — the type system for the whole application.
 *
 * Three faces from one family, because the interface speaks in three voices and
 * they should be related rather than merely adjacent:
 *
 *   Sans   the interface itself — navigation, headings, labels, body copy
 *   Serif  documents, which in practice means a bill's long title
 *   Mono   identifiers — bill citations, and figures that want to line up
 *
 * They replace Inter (interface), a Palatino/Georgia system stack (documents)
 * and a system monospace stack (identifiers). The two system stacks were the
 * real problem: they resolved to different typefaces on macOS, Windows and
 * Linux, so the same page did not look the same on two machines. Everything
 * here is self-hosted, so it now does.
 *
 * Latin subset only. Add the other subsets from @fontsource if the Assembly
 * ever needs them.
