I systematically analyzed all 31 HTML template files and CSS files in the FitPub application to identify dark mode issues. Here's what was found and fixed:

---

## ✅ Fixed Issues

### 1. **Form Elements** (CRITICAL FIX)
**Problem**: Form labels, checkbox labels, and form helper text were showing as dark text on dark backgrounds.

**Affected Pages**:
- Login page (`auth/login.html`)
- Registration page (`auth/register.html`)
- Activity upload (`activities/upload.html`)
- Activity edit (`activities/edit.html`)
- Profile edit (`profile/edit.html`)
- Batch upload (`activities/batch-upload.html`)

**Fix Applied**: Added to `fitpub.css`:
```css
@media (prefers-color-scheme: dark) {
    /* Form elements - Dark Mode Fix */
    .form-label {
        color: var(--dark-text) !important;
    }

    .form-check-label {
        color: var(--dark-text) !important;
    }

    .form-text {
        color: var(--dark-text-muted) !important;
    }
}
```

**Files Modified**:
- `src/main/resources/static/css/fitpub.css` (lines 1018-1029)

---

### 2. **Typography Elements** (CRITICAL FIX)
**Problem**: `<strong>`, `<b>`, and `<small>` tags had no explicit dark mode color, causing dark text on dark backgrounds in activity detail pages.

**Affected Pages**:
- Activity detail page (`activities/detail.html`) - Weather section, additional metrics

**Fix Applied**: Added to `fitpub.css`:
```css
@media (prefers-color-scheme: dark) {
    /* Typography - Dark Mode Fix */
    strong {
        color: var(--dark-text);
    }

    b {
        color: var(--dark-text);
    }

    small {
        color: var(--dark-text);
    }
}
```

**Files Modified**:
- `src/main/resources/static/css/fitpub.css` (lines 1031-1042)

---

### 3. **Batch Upload Status Badges** (HIGH PRIORITY FIX)
**Problem**: Success/Failed/Pending status badges had hardcoded light-mode colors, making them unreadable in dark mode.

**Affected Pages**:
- Batch upload page (`activities/batch-upload.html`)

**Before** (Light Mode Only):
```css
.status-SUCCESS {
    background: #d4edda;  /* Light green */
    color: #155724;       /* Dark green text */
}

.status-FAILED {
    background: #f8d7da;  /* Light red */
    color: #721c24;       /* Dark red text */
}

.status-PENDING, .status-PROCESSING {
    background: #fff3cd;  /* Light yellow */
    color: #856404;       /* Dark yellow text */
}
```

**After** (Dark Mode Added):
```css
@media (prefers-color-scheme: dark) {
    .status-SUCCESS {
        background: rgba(57, 255, 20, 0.25);  /* Neon green with transparency */
        color: #39ff14;                        /* Bright neon green text */
        border: 1px solid #39ff14;
    }

    .status-FAILED {
        background: rgba(220, 53, 69, 0.25);  /* Red with transparency */
        color: #ff6b7a;                        /* Bright red text */
        border: 1px solid #dc3545;
    }

    .status-PENDING, .status-PROCESSING {
        background: rgba(255, 193, 7, 0.25);  /* Yellow with transparency */
        color: #ffc107;                        /* Bright yellow text */
        border: 1px solid #ffc107;
    }
}
```

**Files Modified**:
- `src/main/resources/templates/activities/batch-upload.html` (lines 121-144)

### 4. **404 Error Page** (CRITICAL FIX)
**Problem**: The 404 "Not Found" page had NO dark mode support at all - fully white background with dark text.

**Affected Pages**:
- `error/404.html`

**Fix Applied**: Added comprehensive dark mode styles:
```css
@media (prefers-color-scheme: dark) {
    .error-container {
        background: linear-gradient(135deg, #2d0052 0%, #1a0033 100%);
    }

    .error-card {
        background: #251040;
        color: #e8e8f0;
        border: 3px solid #ff1493;
    }

    .error-title {
        color: #e8e8f0;
    }

    .error-subtitle,
    .error-message {
        color: #a8a8c0;
    }

    .error-suggestions {
        background: #1a0a30;
        border: 2px solid #00ffff;
    }

    .btn-home {
        background: linear-gradient(135deg, #ff1493 0%, #9d00ff 100%);
        border-color: #ff1493;
    }

    .btn-back {
        color: #00ffff;
    }

    .btn-back:hover {
        color: #ff1493;
    }
}
```
