## I assumed

a stat written as a big number with a small unit after it (`<span className="ms-1.5">USDT</span>`) would read "15 USDT" on a Persian page, with the gap between them.

## What happened

the number and the Latin unit form one left-to-right run inside the right-to-left line, so they were laid out together and the unit's start margin ended up on its outer side: the unit ran into the number.

## The fix

the unit is an `inline-block`, which the line treats as one piece, so it keeps its own margin where the line's direction puts it: `<span className="ms-1.5 inline-block …">{stat.unit}</span>` on the Overview, Campaigns, Rate cards, Calendar and Orders.

## Evidence

phase 4, commit 14f166e ("Stat units after a number no longer run into it on Persian pages").
