Subject: [PATCH] Simplify CSS architecture by removing cascade layers and
 !important declarations

- Remove @layer declarations and complex hybrid approach
- Eliminate all !important usage - rely on natural CSS specificity
- Add explicit color declarations to prevent inheritance issues
- Class selectors (0,0,1,0) naturally beat universal selectors (0,0,0,0)
- Fixes white-on-white modal issues on sites with CSS resets
- Works in all browsers without 2022+ cascade layer requirements
- Cleaner, more maintainable CSS architecture

-       
-       HYBRID CSS ARCHITECTURE:
-       
-       This CSS uses a hybrid approach for maximum browser compatibility:
-       
-       1. MODERN BROWSERS: @layer insertr provides cascade layer isolation
-          - Layered styles automatically win over unlayered styles
-          - Clean separation regardless of specificity
-          - Future-proof CSS architecture
-          
-       2. LEGACY BROWSERS: Higher specificity fallback selectors
-          - html body .insertr-* selectors (0,0,3,0) beat universal * (0,0,0,1)
-          - Works in all browsers back to IE6
-          - Ensures consistent behavior across environments
-          
-       This ensures our form elements maintain proper spacing and styling
-       even on sites with aggressive CSS resets like "* {margin:0; padding:0}"

 /**
- * Insertr - The Tailwind of CMS
- * Unified CSS Styles with Cascade Layer Architecture
+ * INSERTR CSS - Centralized Styles for Content Management Interface
+ * 
+ * Architecture: Simple class-based CSS with proper specificity
+ * - Class selectors (0,0,1,0) automatically beat universal selectors (0,0,0,0)
+ * - No cascade layers needed - works in all browsers
+ * - No !important needed - specificity handles conflicts naturally
+ * - Explicit colors prevent inheritance issues
+ * 
+ * Components:
+ * - .insertr-gate: Minimal styling for user-defined gates
+ * - .insertr-auth-*: Authentication controls and buttons  
+ * - .insertr-form-*: Modal forms and inputs
+ * - .insertr-version-*: Version history modal

-       ================================================================= 
-       
-       HYBRID CSS ARCHITECTURE:
-       
-       This CSS uses a hybrid approach for maximum browser compatibility:
-       
-       1. MODERN BROWSERS: @layer insertr provides cascade layer isolation
-          - Layered styles automatically win over unlayered styles
-          - Clean separation regardless of specificity
-          - Future-proof CSS architecture
-          
-       2. LEGACY BROWSERS: Higher specificity fallback selectors
-          - html body .insertr-* selectors (0,0,3,0) beat universal * (0,0,0,1)
-          - Works in all browsers back to IE6
-          - Ensures consistent behavior across environments
-          
-       This ensures our form elements maintain proper spacing and styling
-       even on sites with aggressive CSS resets like "* {margin:0; padding:0}"
