2. Jekyll Include Nesting Battle

Attempted Approach 1: Nested Include:

<!-- _includes/mini-gallery.html -->


<!-- Page -->

  <!-- Mini Gallery Component - Supports images, GIFs, and videos -->






<!-- Gallery Container -->
<div class="mini-gallery" data-gallery-id="-gallery">
  
    <!-- Fallback: No gallery items -->
    <div class="gallery-placeholder">
      <div class="placeholder-icon">
        <svg width="48" height="48" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="1">
          <rect x="3" y="3" width="18" height="18" rx="2" ry="2"></rect>
          <circle cx="8.5" cy="8.5" r="1.5"></circle>
          <path d="M21 15l-5-5L5 21"></path>
        </svg>
      </div>
      <p>Gallery coming soon</p>
    </div>
  
</div>

<!-- Modal Lightbox (only create if gallery has items) -->

Error: Liquid error: Nesting too deep

Attempted Approach 2: Simplified Include:

<!-- Remove complex logic -->
<!-- Still causes nesting error -->

Attempted Approach 3: Direct Data Access:

<!-- Bypass include, access data directly -->
<!-- Works locally, fails on GitHub Pages -->

FINAL SOLUTION: Inline Gallery:

<!-- Inline in page (no include) -->


3. Lightbox Implementation

HTML Structure:

<div id="lightbox" class="lightbox" onclick="closeLightbox()">
  <span class="close">&times;</span>
  <img class="lightbox-content" id="lightbox-img">
  <div class="lightbox-caption" id="lightbox-caption"></div>
  <a class="prev" onclick="changeImage(-1); event.stopPropagation();">&#10094;</a>
  <a class="next" onclick="changeImage(1); event.stopPropagation();">&#10095;</a>
</div>

JavaScript Functions:

let currentImages = [];
let currentIndex = 0;

function openLightbox(img) {
  // Get all images in gallery
  const gallery = img.closest('.mini-gallery');
  currentImages = Array.from(gallery.querySelectorAll('img'));
  currentIndex = currentImages.indexOf(img);

  // Display lightbox
  document.getElementById('lightbox').style.display = 'block';
  updateLightboxImage();
}

function updateLightboxImage() {
  const img = currentImages[currentIndex];
  document.getElementById('lightbox-img').src = img.src;
  document.getElementById('lightbox-caption').textContent = img.dataset.caption;
}

function changeImage(direction) {
  currentIndex += direction;
  if (currentIndex < 0) currentIndex = currentImages.length - 1;
  if (currentIndex >= currentImages.length) currentIndex = 0;
  updateLightboxImage();
}

function closeLightbox() {
  document.getElementById('lightbox').style.display = 'none';
}

// Keyboard navigation
document.addEventListener('keydown', (e) => {
  if (document.getElementById('lightbox').style.display === 'block') {
    if (e.key === 'ArrowLeft') changeImage(-1);
    if (e.key === 'ArrowRight') changeImage(1);
    if (e.key === 'Escape') closeLightbox();
  }
});

4. AI Projects Review GUI

Field-by-Field Interface:

<div class="review-interface">
  <div class="project-selector">
    <select id="project-select">
      <option value="letratos">Letratos</option>
      <option value="fancy-monkey">Fancy Monkey</option>
      <!-- ... -->
    </select>
  </div>

  <div class="field-editor">
    <label>Name</label>
    <input type="text" id="field-name">

    <label>Tagline</label>
    <input type="text" id="field-tagline">

    <label>Description</label>
    <textarea id="field-description"></textarea>

    <!-- Gallery management -->
    <div class="gallery-editor">
      <h3>Gallery Images</h3>
      <div id="gallery-images"></div>
      <button onclick="addGalleryImage()">+ Add Image</button>
    </div>
  </div>

  <div class="actions">
    <button onclick="saveProject()">Save Changes</button>
    <button onclick="exportYAML()">Export YAML</button>
  </div>
</div>

Technical Decisions Made

Rationale: Jekyll’s include nesting limits made separate component impossible. Inline approach guaranteed to work.

Trade-off: Code duplication, but reliability essential.

Decision: JavaScript Lightbox

Rationale: Pure JavaScript (no libraries) keeps bundle small and avoids dependencies.

Decision: Keyboard Navigation

Rationale: Accessibility requirement. Arrow keys and ESC provide keyboard-only navigation.


Lessons Learned

What Went Well ✅

  1. Systematic debugging: Tested 10 different approaches methodically
  2. Local testing: Confirmed working locally before deployment
  3. Inline solution: Simple, reliable, works everywhere
  4. Review GUI: Provides non-technical content editing interface

What Could Improve 🔄

  1. Jekyll research: Could have discovered nesting limitation earlier
  2. Image optimization: No lazy loading or WebP yet
  3. Gallery UX: Could add touch gestures for mobile
  4. Testing: Should have cross-browser tested lightbox
