   flip on <html> produces a correct mirror with no overrides.

   Allowed:   margin-inline / padding-inline / inset-inline /
              border-inline / text-align:start|end / inset-block
   Forbidden: margin-left, padding-right, left, right, float

               design/DESIGN_DECISIONS.md D-06)
