   AutoTrade — Shared Responsive Layer
   ----------------------------------------------------------------------------
   Sits on top of Bootstrap 5.1 (loaded as bootstrap.min.css OR bootstrap.rtl.min.css
   depending on the active culture). Owns:
     - Off-canvas sidebar behavior (mobile drawer / desktop fixed pane) for the
       User & Owner dashboard layouts.
     - Responsive Landing navbar tweaks layered over landing-page.css.
     - RTL/LTR direction-aware spacing so existing CSS keeps working under both.
     - Common topbar / page-content rhythm that adapts to phone, tablet, desktop.
   Visual theme (colors, gradients, fonts) is intentionally NOT touched here —
   that lives in landing-page.css / dashboard.css and remains the source of truth.
