   37. CHART.JS RECOMMENDED PALETTE & OVERRIDES
   ============================================================

   Chart.js colors must be set in JavaScript, not CSS.
   Use these values when configuring charts:

   Chart.defaults.color = '#8893A0';                    // tick label color
   Chart.defaults.borderColor = 'rgba(0,0,0,0.05)';    // grid line color
   Chart.defaults.font.family = "'Inter', -apple-system, BlinkMacSystemFont, 'Segoe UI', system-ui, sans-serif";
   Chart.defaults.font.size = 12;

   Tooltip configuration:
     backgroundColor: '#1C2024'
     titleColor:      '#FFFFFF'
     bodyColor:       '#CCCCCC'
     borderColor:     '#DFE3E8'
     borderWidth:     1
     padding:         12

   Data colors (use in this order):
     coral:   '#C47A5A'    (primary)
     blue:    '#5A7FBA'    (secondary)
     green:   '#4D8B6F'
     purple:  '#7B6BA8'
     yellow:  '#B08C3E'
     grey:    '#9AA3AE'

   Semi-transparent variants (for area fills, bar backgrounds):
     coral:   'rgba(196, 122, 90, 0.12)'
     blue:    'rgba(90, 127, 186, 0.12)'
     green:   'rgba(77, 139, 111, 0.12)'
     purple:  'rgba(123, 107, 168, 0.12)'
     yellow:  'rgba(176, 140, 62, 0.12)'

   Legend:
     labels.padding = 16
     labels.usePointStyle = true
     labels.pointStyleWidth = 12

   Example JS setup:
   ────────────────
   Chart.defaults.color = '#8893A0';
   Chart.defaults.borderColor = 'rgba(0,0,0,0.05)';
   Chart.defaults.font.family = "'Inter', -apple-system, sans-serif";

   Chart.defaults.plugins.legend.labels.padding = 16;
   Chart.defaults.plugins.legend.labels.usePointStyle = true;
   Chart.defaults.plugins.legend.labels.pointStyleWidth = 12;

   const COLORS = {
     coral:  '#C47A5A',
     blue:   '#5A7FBA',

     purple: '#7B6BA8',
