- The title, style indicator and both rails swap sides in RTL through logical
properties (inset-inline-*, margin-inline-*, border-inline-start); LTR
computes the same values. The Display/Context rail keeps its physical
`right` for the credit-clearance model and swaps in rtl.css above 720px.
- rtl.css: no letter-spacing on Arabic (it tears joined letters apart);
Noto Sans Arabic leads the Arabic font stacks so words are not set in a
fixed-pitch fallback; the intel HUD and cockpit instruments stay a
left-to-right instrument overlay; media transport and the radio dial stay
left to right; feed headlines and station names take their own direction;
the moved rail's arrows flip.
- isolate(): a quantity in RTL text (2.7 كم, -18.0°) is wrapped in
first-strong isolates so its digits do not join a neighbouring Latin run.
