 *
 * A · The element's whole content is Latin — the wordmark, the slide counter,
 * the language code, an about-band numeral. The element itself can flip to
 * `ltr`, because there is no RTL word inside it to disturb. But a block that
 * flips to `ltr` also flips where its text starts, which is what stuck the
 * numerals to the left edge of their column; the ones that fill their column
 * get their alignment back below.
 *
 * B · The Latin run sits *inside* an RTL line — `<small>من</small>$500`. Here
 * flipping the container is the bug: it re-orders the Arabic words around the
 * amount, so "من $500" rendered as "$500 من". The isolation belongs to the run
 * alone, which is what `<bdi>` is for. The line keeps the page's direction and
 * only the amount reads left-to-right.
