   Base and utilities
   Reset, document defaults, and the small helpers used across sections.

   Layout across all four stylesheets is written entirely in logical
   properties (inline-start/end, margin-inline, ...) so the Arabic RTL view
   mirrors without a second stylesheet. There is no `left` or `right`
   anywhere in this project's CSS.
