Subject: [PATCH 09/16] feat(theme): implement dark mode theme with toggle,
 persistence, and system preference

- Add theme toggle button to navigation with sun/moon icons
- Implement initTheme() with system preference detection via prefers-color-scheme
- Add localStorage persistence for theme preference across reloads
- Update CSS with smooth transitions for theme changes
- Add comprehensive E2E tests for light/dark mode, toggle, persistence,
  system preference detection, and section styling

- Verify heading hierarchy and ARIA labels on all interactive elements
- Check color contrast ratios meet WCAG AA standards
- Fix CTA button color contrast by changing btn-secondary to btn-neutral

Subject: [PATCH 11/16] feat(performance): add performance tests and
 optimizations for homepage

- Add FCP/LCP measurement tests for fast connections (<1.5s/<2.5s)
- Add 3G network simulation test for critical content load (<2s)
- Add Cumulative Layout Shift (CLS) test (<0.1)
- Add bundle size unit tests (CSS+JS <200KB gzipped)
- Add image optimization tests (SVG icons, explicit dimensions)
- Optimize CSS with content-visibility, contain, and prefers-reduced-motion
- Add lazy loading and explicit width/height on below-fold images
- Add preconnect hint and fetchpriority=high for critical CSS

Subject: [PATCH 12/16] fix: resolve mobile theme toggle and Playwright strict
 mode violations

- Use querySelectorAll in initThemeToggle to attach listeners to both
  desktop and mobile theme toggle buttons
- Use :visible pseudo-class in E2E tests to handle both viewports

+# Dark Mode Implementation with DaisyUI
+
+## Overview
+
+This project uses DaisyUI's theme system for dark mode. DaisyUI provides built-in light and dark themes that are activated by setting `data-theme` on the `<html>` element. All `bg-base-*` and `text-base-*` utility classes automatically adapt.
+
+## When to Use This Skill
+
+Use this skill when users request:
+- Adding dark mode to a DaisyUI/Tailwind project
+- Theme toggle with localStorage persistence
+- System preference detection (prefers-color-scheme)
+- Smooth theme transitions
+
+## Core Capabilities
+
+### 1. Theme Detection and Persistence
+
+Location: `web/src/js/main.js`
+
+```javascript
+function initTheme() {
+  const root = document.documentElement;
+  const savedTheme = localStorage.getItem('theme');
+
+  let theme;
+  if (savedTheme) {
+    theme = savedTheme;
+  } else if (window.matchMedia && window.matchMedia('(prefers-color-scheme: dark)').matches) {
+    theme = 'dark';
+  } else {
+    theme = 'light';
+  }
+
+  root.setAttribute('data-theme', theme);
+
+  // Listen for system preference changes
+  const mediaQuery = window.matchMedia('(prefers-color-scheme: dark)');
+  mediaQuery.addEventListener('change', function(event) {
+    if (!localStorage.getItem('theme')) {
+      const newTheme = event.matches ? 'dark' : 'light';
+      root.setAttribute('data-theme', newTheme);
+    }
+  });
+
+  initThemeToggle();
+}
+```
+
+### 2. Toggle Button Handling
+
+```javascript
+function initThemeToggle() {
+  // IMPORTANT: Use querySelectorAll for multiple toggle buttons (desktop + mobile)
+  const toggleBtns = document.querySelectorAll('[data-testid="theme-toggle"]');
+  if (!toggleBtns.length) return;
+
+  toggleBtns.forEach(function(toggleBtn) {
+    toggleBtn.addEventListener('click', function() {
+      const root = document.documentElement;
+      const currentTheme = root.getAttribute('data-theme') || 'light';
+      const newTheme = currentTheme === 'dark' ? 'light' : 'dark';
+
+      root.setAttribute('data-theme', newTheme);
+      localStorage.setItem('theme', newTheme);
+
+      // Update ALL toggle button icons/labels
+      toggleBtns.forEach(function(btn) {
+        updateToggleLabel(btn, newTheme);
+      });
+    });
+
+    const currentTheme = document.documentElement.getAttribute('data-theme') || 'light';
+    updateToggleLabel(toggleBtn, currentTheme);
+  });
+}
+
+function updateToggleLabel(button, theme) {
+  const isDark = theme === 'dark';
+  button.setAttribute('aria-label', isDark ? 'Switch to light mode' : 'Switch to dark mode');
+  button.setAttribute('title', isDark ? 'Switch to light mode' : 'Switch to dark mode');
+
+  const icon = button.querySelector('.theme-icon');
+  if (icon) {
+    icon.textContent = isDark ? '☀' : '☽';
+  }
+}
+```
+
+### 3. CSS Transitions
+
+Location: `web/src/css/main.css`
+
+```css
+html {
+  transition: background-color 0.3s ease, color 0.3s ease;
+}
+body, .navbar, .hero, .card, .footer, section {
+  transition: background-color 0.3s ease, color 0.3s ease, border-color 0.3s ease;
+}
+```
+
+## Best Practices
+
+- Use `querySelectorAll` not `querySelector` for toggle buttons when there are multiple (desktop + mobile)
+- Remove hardcoded `data-theme="light"` from `<html>` so JS can set it dynamically before render
+- Use DaisyUI semantic colors (`bg-base-100`, `text-base-content`) rather than explicit light/dark classes
+- Check localStorage before system preference — user's explicit choice should override OS settings
+- Update ALL toggle button labels/icons when theme changes, not just the clicked one

+# E2E Color Brightness Testing
+
+## Overview
+
+When testing dark mode or any color-dependent UI feature with Playwright, `getComputedStyle` returns colors in different formats depending on the browser and CSS engine. This skill provides a robust `getBrightness()` helper that normalizes any format to a 0-255 brightness scale.
+
+## When to Use This Skill
+
+Use this skill when users request:
+- Testing CSS colors in E2E tests
+- Handling oklch/oklab color formats from getComputedStyle
+- Writing assertions for dark/light mode color verification
+- Parsing multiple CSS color formats in tests
+
+## Core Capabilities
+
+### 1. Multi-Format Color Brightness Extraction
+
+```javascript
+function getBrightness(colorStr) {
+  if (!colorStr) return null;
+
+  // rgb/rgba: rgb(255, 255, 255) or rgba(255, 255, 255, 0.5)
+  const rgbMatch = colorStr.match(/rgba?\((\d+(?:\.\d+)?),\s*(\d+(?:\.\d+)?),\s*(\d+(?:\.\d+)?)/);
+  if (rgbMatch) {
+    const r = parseFloat(rgbMatch[1]);
+    const g = parseFloat(rgbMatch[2]);
+    const b = parseFloat(rgbMatch[3]);
+    return (r + g + b) / 3;
+  }
+
+  // oklch: oklch(0.278078 0.029596 256.848) — first value is lightness 0-1
+  const oklchMatch = colorStr.match(/oklch\(([\d.]+)/);
+  if (oklchMatch) {
+    return parseFloat(oklchMatch[1]) * 255;
+  }
+
+  // oklab: oklab(0.419385 0.00478227 -0.0474926) — first value is lightness 0-1
+  const oklabMatch = colorStr.match(/oklab\(([\d.]+)/);
+  if (oklabMatch) {
+    return parseFloat(oklabMatch[1]) * 255;
+  }
+
+  // hsl: hsl(210, 100%, 50%)
+  const hslMatch = colorStr.match(/hsl\([\d.]+,\s*[\d.]+%?,\s*([\d.]+)%?\)/);
+  if (hslMatch) {
+    return (parseFloat(hslMatch[1]) / 100) * 255;
+  }
+
+  return null;
+}
+```
+
+### 2. Usage in Playwright Tests
+
+```javascript
+const bodyBg = await body.evaluate(el => {
+  const computed = window.getComputedStyle(el);
+  return computed.backgroundColor;
+});
+
+const brightness = getBrightness(bodyBg);
+expect(brightness).not.toBeNull();
+expect(brightness).toBeGreaterThan(200); // Light background
+```
+
+### 3. Handling Playwright Strict Mode with Multiple Elements
+
+When multiple elements share the same `data-testid`, use the `:visible` pseudo-class:
+
+```javascript
+// Selects only the visible toggle based on viewport
+const toggleBtn = page.locator('[data-testid="theme-toggle"]:visible');
+```
+
+## Best Practices
+
+- Always normalize colors to brightness rather than comparing raw strings
+- Include parsers for oklch and oklab — modern Chromium returns these formats
+- Use empirically-determined thresholds based on your design system
+- Use `:visible` pseudo-class for elements that exist in both desktop and mobile layouts
+
+## Recommended Brightness Thresholds (DaisyUI)
+
+| Context | Threshold |
+|---------|-----------|
+| Light background | > 200 |
+| Dark background | < 100 |
+| Dark text (light mode) | < 120 |
+| Light text (dark mode) | > 180 |
