Swapped digits mark

Rules

• text-warning in the row style (semibold), underlined with border-width-strong (2px) at space-2xs from the text. The underline means it never relies on color alone.
• Digits only: never a comma or the decimal point. "$12.34" meant as "$13.24" marks the 2 and the 3 on either side of the point.
• On both amounts in the sentence: the likely amount (bold) and the amount as entered. The row's own amount stays plain.
• For the eye only. The marks split an amount into pieces that a screen reader can read apart, so the marked sentence is hidden from screen readers and a plain copy, with whole amounts, is read instead.
• Amber here means an oddity to look at, as the warning band beside it.
