   Title:    FX Trader - Dashboard Stylesheet
   Version:  1.2.2
   Filename: styles.css
   Folder:   C:\FXTrader\assets\css
   -----------------------------------------------------------------
   Purpose:  Foundational stylesheet for the FX Trader dashboard.
             v1.0.11: Forced vertical scrollbar to 24px.
             v1.0.12: Adds Firefox-specific scrollbar properties 
                       (scrollbar-width: thick) to the body tag to 
                       force wide scrollbars in Firefox Private Mode.
             v1.1.1: Reduced .pair-select and .sig-cell sizes to 
                       fit all pairs on screen without truncation.
                       Adjusted header wrapping for swapped layout.
             v1.2.0: Increased .sig-cell min-width and padding to 
                       prevent cramping of pair names and scores.
             v1.2.1: Increased font-size and boldness of B/S scores 
                       in the signal overview cells.
             v1.2.2: Reduced bt-stat-item min-width to ensure all 
                       8 backtest result boxes fit on one line.
   Dependencies:
     - None (pure CSS, loaded by index.php)
