/* ============================================================================
 * Tutur Notes — site styles
 *
 * The palette is lifted from the app's default "Ember" theme so the site and
 * the product read as one thing: burnt orange (#B15013) on warm paper, near
 * black text, generous type. Dark mode mirrors the app, which lifts the accent
 * to #E07B3C because #B15013 does not clear the contrast floor on near black.
