/* Inter Variable, split the way Google Fonts splits it: a visitor fetches the
 * 62 KB latin file and nothing else, and the rest arrive only if a shared item
 * actually contains those scripts. Not subset to the glyphs this page's own
 * strings use — title, username, password and note come from someone else's
 * vault and can be in any script.
 *
 * Declaration order is load-bearing: CSS Fonts 4 checks the LAST matching
 * @font-face first, so whichever file should win a shared codepoint goes last.
 * latin-ext is declared first because it is the biggest (106 KB) and overlaps
 * both vietnamese and cyrillic-ext; letting it win would make a Vietnamese
 * note pull 106 KB for Đ and ơ that the 12 KB vietnamese file already has.
 * latin goes last so the handful of codepoints it shares cost nothing - it is
 * loaded on every page anyway.
