/* نبرة — the interfaces layer.
 *
 * The identity is Najdi: the gypsum-white and mud-brick of Diriyah, its wall
 * crenellations as section dividers, Saudi green spent only where it means
 * something, and the wordmark in Ruqʿah — the handwriting of Saudi shop signs,
 * because the product is a shop's own voice.
 *
 * Every inline-axis property is logical (margin-inline-start, text-align:
 * start, inset-inline-end...). That is the whole of the RTL strategy: the page
 * is designed right-to-left first, and the English mirror falls out of the
 * same stylesheet with no [dir] overrides to drift out of sync. User content
 * (transcripts) additionally isolates with <bdi>, so a Latin order code inside
 * an Arabic sentence cannot reorder its line.
