/*
 * QuranStream — site styles.
 *
 * The palette is taken from the app's own artwork: the deep teal and cream of
 * the logo, and the gold of the splash frame. Nothing here is invented, so the
 * site and the app read as one thing.
 *
 * Arabic is the default and the document is RTL. Every rule that could hard-code
 * a side uses logical properties (inline-start/end, margin-inline) so the
 * English LTR mode is the same stylesheet, mirrored by the browser rather than
 * by a second set of rules.
