   LEVIS VISION — BASE
   Reset, typography, bidirectional foundation, global surfaces.

   BIDI POLICY
   Every directional value in this project uses CSS logical
   properties (inline-start/end, margin-inline, inset-inline).
   Physical left/right appears ONLY where the property is
   genuinely physical — box-shadow offsets, background angles,
   and transform translations that mirror via [dir] overrides.
