 *
 * ============================================================================
 * CHANGELOG
 * ============================================================================
 *
 * v1.0.012 - 2026-02-12 - REMOVE HARDCODED CUSTOM PROPERTY FROM BODY
 *   - [FIX] Removed --active-tab-color: #7b6f96 from body CSS rule
 *   - [REASON] CSS rule was overriding inline style on body tag

 *   - [FIX] Admin page .canvas divs now force background color with !important
 *   - [FIX] Overrides inline styles (e.g., background: #f0f7ff) on canvas boxes
 *   - [ADD] Transparent background for .canvas-body (removes light blue border-left)
 *   - [ADD] White text color for all canvas content
 *   - [RESULT] Canvas boxes now match active tab color (blue for RezCall, teal for RezInsights, etc.)
 *
 * v1.0.010 - 2026-02-11 - WHITE BACKGROUND FOR INDEX, COLORED FOR ADMIN
 *   - [FIX] Index.php body-content now white (not colored)
 *   - [FIX] Only admin.php tab content areas get colored backgrounds
 *   - [CHANGE] Use body.admin-page class to differentiate page styles
 *   - [CHANGE] Section titles dark on white (index), white on colored (admin)
 *   - [CHANGE] Tables maintain white background everywhere
 *   - [RESULT] Index.php clean white interface, admin.php colored per tab
 *
 * v1.0.009 - 2026-02-11 - FOLDER-STYLE TABS WITH CORRECT LAYOUT
 *   - [FIX] Body-canvas reverted to white (only content area colored)
 *   - [FIX] Nav-sidebar reverted to white background with dark text
 *   - [FIX] Footer-canvas reverted to white
 *   - [FIX] Only body-content div gets colored background (right side)
 *   - [IMPROVE] Folder tab styling with slanted right edge via clip-path
 *   - [ADD] Tab colors match background: RezStack #7b6f96, RezCall #3B91E6, RezInsights #61A4AB, RezPost #AB6861
 *   - [RESULT] Header/Nav/Footer white, content area colored, folder-style tabs with slanted edges
 *
 * v1.0.008 - 2026-02-11 - FOLDER-STYLE TABS WITH COLOR THEMING
 *   - [ADD] Folder-style tab design with slanted edges (clip-path)
 *   - [ADD] Tab colors: RezStack #7b6f96, RezCall #3B91E6, RezInsights #61A4AB, RezPost #AB6861
 *   - [ADD] Body background color changes with active tab (CSS custom property --active-tab-color)
 *   - [ADD] Tab button styling with hover and active states
 *   - [CHANGE] Tab text color to black for better contrast on colored backgrounds
 *   - [ADD] Tab transition effects on click
 *   - [ADD] Body color applies to body-canvas and footer-canvas backgrounds
 *   - [RESULT] Folder-style tabs match selected color theme throughout page
 *
 * v1.0.007 - 2026-02-11 - COMPLETE STYLING MERGE FROM SUPER-ADMIN
 *   - [MERGE] All CSS from super-admin.php embedded styles (lines 64-416)
 *   - [FIX] Canvas elements now WHITE (visible) on purple gradient background
 *   - [ADD] Header-right styling for user name and badge
 *   - [ADD] Badge-admin styling (.badge-admin class)
 *   - [ADD] Complete table styling
 *   - [ADD] Modal styling (approve/edit)
 *   - [ADD] Alert styling (success/error)

 *   - [ADD] Footer styling with flex layout

 *   - [RESULT] Single complete CSS file for all pages
 *
 * v1.0.006 - 2026-02-11 - ATTEMPTED SYNTAX FIX
 *   - Had orphaned CSS properties causing parser to break
 *   - Gradient showed but canvases were off-white, blocking view
 *
 * v1.0.005 - 2026-02-10 - INITIAL SHARED CSS
 *   - Extracted from index.php embedded styles
 *   - Incomplete - missing many necessary styles
