Subject: fix: header sticky positioning regression

Changed header from sticky to fixed positioning and added proper margin offset
(mt-20) to main element to prevent content from being covered. The fixed header
now stays at the top during scroll while content renders below it properly.

- Fixed header: changed from sticky to fixed with left-0 right-0 full width
- Main spacing: added mt-20 margin-top with relative z-10 preserved
- Restored z-index layering for content positioning

Also added Week 3 completion documentation and Week 4 planning files:
- WEEK3-COMPLETION.md: Comprehensive audit of Week 3 implementation
- WEEK3-4-TRANSITION.md: Handoff document with git workflow
- WEEK4-PLAN.md: Full technical roadmap for Week 4 forms & interactions
- PROGRESS-STATUS-WEEK4.txt: Updated cumulative progress tracking
- Updated HANDOFF.md with Week 3 summary and Week 4 readiness

+# Week 4 Plan: Forms & Interactions
+**Date Started:** 2026-04-16 | **Branch:** `week-4-forms` | **Estimated Duration:** 6–8 hours
+
+---
+
+## 🎯 Week 4 Objectives
+
+### 1. Form Component System
+Build a reusable form component library with accessibility and styling.
+
+#### Components to Create:
+- **Input Fields** (`.form-input`)
+  - Text input, email, password, number
+  - States: default, focus, invalid, disabled
+  - Placeholder and label styling
+  - Error message display
+  - Character count support (optional)
+
+- **Textareas** (`.form-textarea`)
+  - Resizable or fixed height
+  - Auto-expanding variant
+  - Character limit indicator
+  - Syntax highlighting placeholder (optional)
+
+- **Select Dropdowns** (`.form-select`)
+  - Native `<select>` styling
+  - Multi-select support
+  - Custom styled variant (Alpine.js powered)
+  - Accessible keyboard navigation
+
+- **Checkboxes & Radio Buttons** (`.form-checkbox`, `.form-radio`)
+  - Custom styled (not browser defaults)
+  - Grouped layouts (inline, stacked)
+  - Label association (proper `<label for="">`)
+  - Accessible keyboard navigation
+
+- **Form Groups** (`.form-group`)
+  - Label + input + error message layout
+  - Spacing consistency
+  - Validation state indicators
+  - Help text support
+
+#### Styling Requirements:
+- ✅ Dark mode support (all components)
+- ✅ Light mode support (all components)
+- ✅ Focus indicators (2px ring, visible)
+- ✅ Error states (red outline, error message)
+- ✅ Disabled states (opacity, cursor)
+- ✅ WCAG AA contrast verified
+- ✅ Touch targets ≥44px (mobile)
+- ✅ Consistent spacing (8px grid)
+
+---
+
+### 2. Form Layouts & Patterns
+Implement common form patterns using the component library.
+
+#### Layouts:
+- **Single Column**
+  - Contact form (name, email, message)
+  - Newsletter signup (email, subscribe button)
+  - Search form (input, submit)
+
+- **Multi Column**
+  - Registration form (2–3 columns on desktop, 1 on mobile)
+  - Filter/search form (label + input grids)
+
+- **Inline Forms**
+  - Search bar (icon + input + button)
+  - Newsletter widget (email + button)
+
+#### Validation Patterns:
+- **Client-side** (Alpine.js)
+  - Required field checking
+  - Email format validation
+  - Password strength indicator
+  - Conditional field visibility (show/hide based on selection)
+
+- **Server-side Integration**
+  - PHP contact form endpoint (`contact.php`)
+  - Error message display
+  - Success/confirmation messaging
+  - CSRF token handling (if applicable)
+
+#### Form States:
+- Empty (pristine)
+- Focused (active field)
+- Filled (has value)
+- Invalid (validation error)
+- Submitting (loading spinner)
+- Submitted (success message)
+
+---
+
+### 3. Modals & Overlays
+Build reusable modal components for alerts, confirmations, and content.
+
+#### Modal Variants:
+- **Alert Modal** (`.modal-alert`)
+  - Single action button (OK, Close)
+  - Message display
+  - Optional icon
+
+- **Confirmation Modal** (`.modal-confirm`)
+  - Two action buttons (Confirm, Cancel)
+  - Title + message
+  - Danger state (red button for destructive actions)
+
+- **Content Modal** (`.modal-content`)
+  - Close button (X)
+  - Title + body + footer
+  - Large, medium, small sizes
+  - Scrollable content
+
+#### Modal Features:
+- ✅ Backdrop (semi-transparent overlay)
+- ✅ Keyboard handling (Escape to close, Tab trap)
+- ✅ Focus management (focus inside modal, restore on close)
+- ✅ Animation (fade in/out, slide up)
+- ✅ Responsive (full-screen on mobile, centered on desktop)
+- ✅ WCAG compliant (role="dialog", aria-labelledby)
+
+#### Alpine.js Integration:
+- `x-data="{ open: false }"`
+- `@click.outside="open = false"` (close on background click)
+- `@keydown.escape="open = false"` (close on Escape)
+- Smooth transitions with `x-transition`
+
+---
+
+### 4. Interactive Patterns
+Enhance user interactions with feedback and validation.
+
+#### Patterns:
+- **Form Submission Feedback**
+  - Loading spinner during submission
+  - Success toast/notification
+  - Error notification with retry
+  - Progress indicator (for long forms)
+
+- **Inline Validation**
+  - Real-time feedback as user types
+  - Email format validation
+  - Password strength meter
+  - Character count display
+
+- **Loading States**
+  - Spinner component (animated SVG or CSS)
+  - Button disabled state during submission
+  - Loading overlay (for full-page actions)
+
+- **Toast Notifications**
+  - Success (green)
+  - Error (red)
+  - Info (blue)
+  - Warning (amber)
+  - Auto-dismiss (5 seconds)
+  - Manual close button
+
+- **Tooltips**
+  - Hover to show/hide
+  - Fixed positioning (stays visible)
+  - Arrow pointing to target
+  - Dark/light mode support
+
