/* DIRECTION-AGNOSTIC BY CONSTRUCTION. Everything on the inline (writing-direction) axis is expressed with logical properties - margin-inline-start rather than margin-left, text-align: start rather than left, border-inline-start rather than border-left - so `dir="rtl"` on (set from the language object in lang/
.json) mirrors the entire layout with no second stylesheet
   and no per-direction overrides to keep in step.
   Block-axis properties (margin-bottom, border-top, padding-block) are
   left as-is deliberately: they don't change meaning between LTR and RTL
   in a horizontal writing mode, so rewriting them would be churn that
   makes the diff harder to review without buying anything. */
