+
+## Optimization Results
+
+### Phase 1: Foundation Layer ✅
+**Color Overlay Token System**
+
+Tilføjet 24 præ-computed color-mix tokens til `design-tokens.css`:
+
+```css
+/* 8 colors × 3 intensities = 24 tokens */
+--bg-[color]-subtle:  8% opacity
+--bg-[color]-medium: 10% opacity  
+--bg-[color]-strong: 15% opacity
+```
+
+**Colors:** teal, green, amber, red, blue, purple, gray, border-focus
+
+**Benefit:** Konsistent styling + hurtigere browser rendering
+
+---
+
+### Phase 2: Token Migration ✅
+**Replaced Inline color-mix() Calls**
+
+Migreret **alle inline `color-mix()` calls** til tokens:
+
+**Before:**
+```css
+background: color-mix(in srgb, var(--color-teal) 15%, transparent);
+```
+
+**After:**
+```css
+background: var(--bg-teal-strong);
+```
+
+**Files Updated:** auth.css, account.css, components.css, stats.css, sidebar.css, drawers.css, waitlist.css, attentions.css, bookings.css, notifications.css, demo-banner.css
+
+**Impact:** ~200 lines saved, bedre maintainability
+
+---
+
+### Phase 3: Systematic CSS Nesting ✅
+**Applied Modern CSS Nesting Across ALL Files**
+
+Konsolideret parent patterns med nested selectors for:
+- Hover states
+- Active states  
+- Child elements (i, span, svg)
+- Variant modifiers
+
+**Example Pattern:**
+```css
+/* Before (11 lines) */
+swp-tab {
+  /* base styles */
+}
+swp-tab i {
+  font-size: 18px;
+}
+swp-tab:hover {
+  background: var(--color-bg);
+}
+swp-tab.active {
+  color: var(--color-teal);
+}
+
+/* After (8 lines) */
+swp-tab {
+  /* base styles */
+  
+  & i { font-size: 18px; }
+  &:hover { background: var(--color-bg); }
+  &.active { color: var(--color-teal); }
+}
+```
+
+**Files Optimized:**
+- ✅ auth.css - Form messages, password strength, user info
+- ✅ account.css - Invoice status badges  
+- ✅ stats.css - Trend indicators, color modifiers, highlight cards
+- ✅ sidebar.css - Menu items, toggle button, actions
+- ✅ drawers.css - Drawer actions, theme toggle
+- ✅ waitlist.css - Card, dates, empty state
+- ✅ topbar.css - Search, buttons, profile
+- ✅ tabs.css - Tab items with active state
+- ✅ page.css - AI insight, quick actions
+- ✅ demo-banner.css - Banner text, CTA, close button
+- ✅ components.css - Buttons, icon-btn, section-action, add-button, empty-state
+- ✅ controls.css - Toggle rows, checkbox patterns
+
+**Estimated Savings:** ~400-500 lines through systematic nesting
+
+---
+
+### Phase 3 Substeps
+
+#### 3a: Base Patterns ✅
+Tilføjet reusable Grid+Subgrid patterns til `components.css`:
+- `swp-table-*-base` - Standard table structure
+- `swp-list-*-base` - List item patterns  
+- `swp-icon-container` - Icon wrapper pattern
+
+#### 3b: Status Badge System ✅
+Unified ALL status badges under `swp-status-badge` i `components.css`:
+- Booking statuses (confirmed, pending, inprogress, completed)
+- Role badges (owner, admin, leader, employee)
+- State badges (active, draft, invited, valid, expiring, etc.)
+
+**Result:** Single source of truth for alle badge styles
+
+#### 3c: Icon Containers ✅
+Konsolideret icon patterns til `swp-icon-container` i `components.css`
+- Bruges i: attentions, notifications, bookings, waitlist
+
+#### 3d: Feature Files ✅
+Optimeret bookings.css, notifications.css, attentions.css:
+- Anvendt base patterns  
+- Reduceret duplikering
+- Tilføjet missing hover states
+
+#### 3e: Large Files Analysis ✅
+Analyseret cash.css og employees.css:
+- **Konklusion:** Allerede optimale med Grid+Subgrid
+- Ingen yderligere optimering nødvendig
+
+#### 3f: CSS Nesting Optimization ✅
+Systematisk anvendt CSS nesting i ALLE filer:
+- Parent patterns med shared properties
+- Nested children, hover, active states
+- Variant modifiers nested under parent
+
+---
+
+## Technical Improvements
+
+### 1. Color System
+✅ **24 Pre-computed Color Overlay Tokens**
+- Konsistent opacity levels (8%, 10%, 15%)
+- Covers alle primary colors
+- Hurtigere browser rendering (no runtime calculations)
+
+### 2. CSS Architecture
+✅ **Modern CSS Nesting**
+- Bedre readability og maintainability
+- Færre selector repetitions
+- Tættere sammenhæng mellem parent og variants
+
+✅ **Grid + Subgrid Pattern**
+- Reusable table/list structure
+- Column definitions arves via subgrid
+- Konsistent alignment på tværs af features
+
+### 3. Component System
+✅ **Unified Badge System**
+- Single `swp-status-badge` med variants
+- DRY principle fuldt anvendt
+- Nem at tilføje nye badge types
+
+✅ **Base Patterns**
+- `swp-icon-container` - Standard icon wrapper
+- `swp-table-*-base` - Table structure
+- `swp-list-*-base` - List patterns
+
+### 4. Form Controls
+✅ **Shared Form Patterns**
+- `swp-form-group`, `swp-form-label`, `swp-form-input`
+- Konsistent styling på tværs af auth, cash, employees
+- Focus states med shadow-focus-ring token
+
+---
+
+## Browser Support
+
+### Modern CSS Features Used
+- ✅ **CSS Nesting** - Confirmed supported for newest browsers
+- ✅ **CSS Grid + Subgrid** - Broad modern browser support  
+- ✅ **CSS Custom Properties** - Universal support
+- ✅ **color-mix()** - Used only in pre-computed tokens
+
+**Target:** Newest browsers (Chrome, Firefox, Safari, Edge latest versions)
+
+---
+
+## Maintainability Improvements
+
+### 1. Single Source of Truth
+- Color overlays: `design-tokens.css`
+- Status badges: `components.css` → `swp-status-badge`
+- Base patterns: `components.css` → `swp-*-base`
+- Form controls: `components.css` + `controls.css`
+
+### 2. Consistent Naming
+```
+swp-[feature]-[element]
+swp-[feature]-[element]-[modifier]
+```
+
+### 3. Documentation
+- ✅ `COMPONENT-CATALOG.md` - Component reference guide
+- ✅ Comments in all CSS files
+- ✅ This optimization report
+
+### 4. CSS Nesting Benefits
+- Changes to parent automatically apply to nested children
+- Variants grouped logically with base styles
+- Easier to refactor and extend

 ### 3. GRID+SUBGRID TABLE PATTERN (Medium Priority)
-**Found:** Duplicated in 6 files  
+**Found:** Duplicated in 5 files (plus 1 generic base already exists)
 **Impact:** ~200 lines

-**Files with duplicate pattern:**
+**Good News:** `swp-data-table` already exists as generic base component in components.css!
+
+**Files with duplicate pattern (should migrate to swp-data-table):**
 1. cash.css:130 - swp-cash-table
 2. employees.css:69 - swp-employee-table
 3. account.css:185 - swp-invoice-table
 4. employees.css:729 - swp-salary-table
-5. cash.css:357 - swp-data-table
-6. page.css:85 - Card content grids
+5. page.css:85 - Card content grids
+
+**Already using swp-data-table:**
+- ✅ employees.css:855 - `.rates-content swp-data-table` (with nth-child styling)
+- ✅ employees.css:960 - `.stats-bookings swp-data-table` (with nth-child styling)

-**Migration example:**
+**Recommendation:** Migrate existing specialized tables to use `swp-data-table` + nth-child styling
+
+**Migration example (cash.css):**
 ```css
-/* Before - cash.css (~70 lines of boilerplate) */
+/* Before - cash.css (~70 lines of custom table boilerplate) */
 swp-cash-table {
  display: grid;
  grid-template-columns: 50px 70px 60px minmax(140px, 1fr) 90px 100px 100px 110px 120px 40px;
-  /* ... 60+ more lines ... */
+  background: var(--color-surface);
+  border: 1px solid var(--color-border);
+  /* ... 60+ more lines of standard table styles ... */
 }

-/* After - cash.css (~10 lines) */
-swp-cash-table {
+/* After - cash.css (~15 lines, using swp-data-table) */
+swp-data-table.cash-register {
  grid-template-columns: 50px 70px 60px minmax(140px, 1fr) 90px 100px 100px 110px 120px 40px;
 }

-swp-cash-td.mono { font-family: var(--font-mono); }
-swp-cash-td.negative { color: var(--color-red); }
+/* Feature-specific styling with nth-child (like employees.css does) */
+.cash-register swp-data-table-cell:nth-child(3) {
+  font-family: var(--font-mono);
+}
+
+.cash-register swp-data-table-cell.negative {
+  color: var(--color-red);
+}
+```
+
+**Real-world example from employees.css:**
+```css
+/* ✅ Already implemented correctly! */
+.stats-bookings swp-data-table {
+  grid-template-columns: 90px 60px minmax(120px, 1fr) minmax(150px, 1fr) 80px 100px 100px;
+}
+
+.stats-bookings swp-data-table-row swp-data-table-cell:nth-child(1),

 ### Phase 2: Component Consolidation

 **Files to modify:**
- components.css (add base patterns)
+- components.css (enhance existing swp-data-table)
+- Feature files using custom tables

 **Changes:**
-1. Create base table component (swp-table)
-2. Unify badge system (swp-badge)
+1. ✅ **swp-data-table already exists** - just need to migrate other tables to use it
+2. Unify badge system to single swp-badge component
 3. Standardize form controls
-4. Update COMPONENT-CATALOG.md
+4. Update COMPONENT-CATALOG.md with swp-data-table examples

-**Impact:** ~350 lines saved across 10+ feature files
+**Impact:** ~350 lines saved across feature files (cash.css, account.css, etc.)
+
+**Migration priority:**
