/* rdsm.tumee.org — shared stylesheet
 *
 * One file for all six pages. No external fonts, scripts or images anywhere on
 * this site: the whole thing is HTML, this stylesheet and site.js.
 *
 * Sans throughout, not the Charter serif the main tumee.org pages use. Charter's
 * Cyrillic coverage is inconsistent across the systems it falls back through, and
 * half this site is Mongolian — a heading that silently reflows into a different
 * face mid-sentence is worse than not using a serif at all.
 *
 * The palette is the institutional white-and-blue that national health bodies
 * and the international rare-disease alliances all converge on. It is a
 * deliberate genre signal, not a copy of anyone's brand: the mark, the type and
 * the layout here are this site's own.
 *
 * Bilingual rule: every translatable node is duplicated, tagged data-l="mn" or
 * data-l="en", and the inactive one is hidden by the selector at the bottom of
 * this file. That is a CSS rule, not a script, so the page is readable in
 * Mongolian (the markup's own lang) before site.js runs or if it never does.
