/*
 * Myanmar Unicode face, shared by the frontend and the admin.
 *
 * This replaces Zawgyi-One, which was pulled from mmwebfonts.comquas.com. Zawgyi
 * is not a Unicode encoding: it reuses codepoints the Unicode standard assigns to
 * Shan, Mon and Rumai Palaung (U+1060-U+109F) for its own Burmese glyph variants,
 * so Zawgyi text sorts, searches and reads wrong everywhere outside a Zawgyi font.
 * Myanmar switched to Unicode on 1 October 2019 and Zawgyi has had no maintainer
 * since. The stored content was converted with the Rabbit rule set; see
 * App\Console\Commands\ConvertZawgyiToUnicode.
 *
 * Self-hosted rather than served from a font CDN: the previous setup put a single
 * third-party host in the critical rendering path of every page.
 *
 * One file covers every weight - it is a variable font, hence `font-weight: 100
 * 900`. The URL is root-absolute because this file is concatenated into bundles
 * that sit at two different directory depths under public/, and Apache's document
 * root is public/ (see Procfile).

 * Base stack. This is what actually puts Myanmar text on the face declared

 *
 * The frontend overrides this from design/style.css, which names Proxima Nova
 * for Latin; what is left here is the admin, where the Myanmar content is
 * actually written.
 *
 * The tail of this stack is ArchitectUI's own body font, restated verbatim so the
 * theme's Latin rendering is unchanged. Because the @font-face above declares a
 * unicode-range, the leading entry only ever claims Myanmar codepoints.
 * Pyidaungsu, Myanmar Text and Padauk are locally-installed Unicode fallbacks for
 * the case where the woff2 fails to load.
