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) -->
<!-- Gallery JavaScript (Progressive Enhancement) -->

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">×</span>
<img class="lightbox-content" id="lightbox-img">
<div class="lightbox-caption" id="lightbox-caption"></div>
<a class="prev" onclick="changeImage(-1); event.stopPropagation();">❮</a>
<a class="next" onclick="changeImage(1); event.stopPropagation();">❯</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
Decision: Inline Gallery Over Include
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 ✅
- Systematic debugging: Tested 10 different approaches methodically
- Local testing: Confirmed working locally before deployment
- Inline solution: Simple, reliable, works everywhere
- Review GUI: Provides non-technical content editing interface
What Could Improve 🔄
- Jekyll research: Could have discovered nesting limitation earlier
- Image optimization: No lazy loading or WebP yet
- Gallery UX: Could add touch gestures for mobile
- Testing: Should have cross-browser tested lightbox
Project Status
Gallery System: ✅ OPERATIONAL
