   Trade ERP — application stylesheet
   --------------------------------------------------------------------------
   Bilingual: the <html> element carries dir="ltr"|"rtl" and lang="en"|"ar".
   Everything below is written with CSS *logical* properties
   (inline-start / inline-end) so one rule serves both directions. The only
   [dir="rtl"] overrides in this file are for things logical properties
   genuinely cannot express: mirroring glyphs/icons and a couple of
   background-position values. There are no `left:` / `right:` layout rules.

   Design intent: a dense, calm, high-legibility internal tool. Merchandisers,
   buyers, warehouse staff and accountants stare at this for eight hours, so:
   compact type, 1px borders instead of shadows, one accent hue, and data
   tables treated as the primary surface rather than an afterthought.
