Complete Sci-Fi UI demo with six commits and Pages deployment

[Copilot]

This PR completes and publishes the Sci-Fi UI demo with three fully functional theme variants (LCARS/Star Trek, Star Wars, Cyberpunk) following the exact specification with six clearly separated commits.

🎨 Demo Preview

The demo features three distinct sci-fi themes with live switching and persistent state:

LCARS (Star Trek)	Star Wars	Cyberpunk

📦 Implementation Details

Commit Structure

The implementation follows a logical progression across six commits:

1. structure — Established directory layout with .gitkeep files for empty folders (images, fonts, audio) and created placeholder SVG assets (lcars-panels.svg, hologram-activation.svg) alongside the existing hud-grid.svg. Verified the root redirect at /docs/index.html uses location.replace('scifi-ui/') for proper navigation.

2. styles — Implemented precise CSS values per theme:

   • base.css: Added visible :focus-visible outlines (≥2px), comprehensive prefers-reduced-motion fallbacks, and .progress .bar initial state with transition: none; width: 0
   • lcars.css: Exact variables --lcars-main:#FF9A3C, --lcars-accent:#8C6AFF, panel-glow:rgba(255,154,60,0.12), gradient progress bar, and keyframes lcars-sheen 1.6s linear infinite
   • starwars.css: Variables --sw-main:#2EE6FF, --sw-accent:#90F0FF, grid-glow:rgba(46,230,255,0.08), gradient linear-gradient(90deg,rgba(46,230,255,0.12),rgba(144,240,255,0.06)), and keyframes sw-grid 2s linear infinite with stroke-dashoffset animation
   • cyberpunk.css: Variables --cp-magenta:#FF2EC0, --cp-cyan:#00E5FF, --cp-yellow:#FFD500, gradient linear-gradient(90deg,var(--cp-cyan),#8c2eff), and keyframes cp-glitch 1.2s steps(6) infinite with subtle hue-rotate pulse
   • Added commented font preload tags in index.html as examples for future licensed fonts

3. scripts — Implemented accessible, theme-aware JavaScript behavior:

   • theme-switcher.js: Theme map linking stylesheets, setTheme() function that swaps link#theme-css, sets data-theme on document root, persists to localStorage (key: scifi-theme), updates aria-pressed on buttons, toggles .loader-sample visibility where data-theme-sample matches, and dispatches CustomEvent('theme:changed')
   • preloader.js: Added role="status" and aria-live="polite" for accessibility, implemented staged loop 0→100 with 60-90ms jitter (theme-specific: LCARS 6%, Star Wars 5%, Cyberpunk 8% per step), respects prefers-reduced-motion (immediate completion), updates aria-valuenow, and dispatches preloader:done event
   • anim-controller.js: activateThemeAnimations() applies per-theme transitions (LCARS: 1.6s cubic-bezier(.2,.9,.2,1), Star Wars: 1.8s ease-in-out with HUD class toggle, Cyberpunk: 1.2s steps(6,end) with glitch class), onPreloaderDone sets visible .loader-sample .bar to width:100% and adds active class

4. assets placeholders — Created assets/README.md documenting all placeholder SVGs as original works with no unlicensed IP. Verified .gitkeep files remain in empty directories (images, fonts, audio) to maintain structure without violating licensing.

5. README — Updated comprehensive documentation including:

   • GitHub Pages setup: Source main → /docs, URL https://hutoczky.github.io/FormatX/scifi-ui/
   • Complete asset inventory with license status (all original placeholders, system font stacks)
   • Local development steps using Python or Node HTTP servers
   • Lighthouse CI usage with Core Web Vitals thresholds (LCP < 2.5s, CLS < 0.10, TTFB < 600ms)
   • Updated acceptance checklist and testing procedures

6. CI — Enhanced .github/workflows/ci.yml with:

   • Core Web Vitals assertions in lighthouserc.json (largest-contentful-paint, cumulative-layout-shift, server-response-time)
   • Automated PR comment posting Lighthouse results with scores table and Core Web Vitals metrics
   • Pages deployment notification echoed on merge to master
   • Proper permissions (pull-requests: write) for comment automation

🚀 GitHub Pages Configuration

Deployment Setup:

• Source: main branch → /docs folder
• Demo URL: https://hutoczky.github.io/FormatX/scifi-ui/
• Root redirect: /docs/index.html forwards visitors to scifi-ui/ subdirectory

📄 Asset License & Compliance

All assets are original work:

• svgs/hud-grid.svg — Star Wars-style HUD grid overlay
• svgs/lcars-panels.svg — LCARS-style panel decorations
• svgs/hologram-activation.svg — Holographic activation effect

No unlicensed IP:

• ❌ No trademarked logos or symbols
• ❌ No copyrighted imagery from films/shows
• ❌ No licensed sound effects or music
• ❌ No proprietary typefaces

Font handling:

• System font stacks used throughout (Eurostile, Orbitron, OCR-A fallbacks)
• Preload tags commented in index.html with instructions for adding licensed fonts
• .gitkeep placeholder in assets/fonts/ directory

✅ Key Features

• Live Theme Switching: Change themes without page reload, persisted to localStorage
• Accessibility: Full ARIA support, keyboard navigation, focus indicators (≥2px), reduced-motion compliance
• Progressive Enhancement: Base functionality works without JavaScript (LCARS theme)
• Performance: Lighthouse CI enforces 90%+ scores with Core Web Vitals thresholds
• Theme-Specific Animations: Each theme has unique transitions and visual effects
• Custom Events: JavaScript modules communicate via theme:changed and preloader:done events

🧪 Testing

Manual browser testing confirms:

• ✅ All three themes switch correctly and persist across page reloads
• ✅ Preloader shows with accessible progress updates
• ✅ ARIA attributes properly set (role, aria-pressed, aria-valuenow)
• ✅ Focus indicators visible for keyboard navigation
• ✅ No console errors or warnings
• ✅ Theme-specific animations activate correctly

📋 What's Next

After merge:

1. Lighthouse CI will run and post detailed results as PR comment
2. GitHub Pages will automatically deploy from /docs
3. Demo will be live at https://hutoczky.github.io/FormatX/scifi-ui/
4. Static deployment workflow will publish the updated site

The demo showcases production-ready patterns for theme switching, accessibility, and progressive enhancement—all without using unlicensed assets.
