feat: complete Hugo theme implementation from mockups

Transform all production-ready mockup files into a fully functional Hugo theme
with all design patterns, components, and interactivity. Implements the complete
plan: token alignment, global shell, homepage, articles section, single article
views, photo gallery, static pages, and 404 page.

Changes:
- Phase 0: Token alignment (--color-* → --type-*, add spacing/z-index/timing scales)
- Phase 1a: Global shell (baseof.html, hamburger menu, theme toggle, matrix rain)
- Phase 1b: Homepage (hero layout, glitch/typing/scroll-reveal effects)
- Phase 1c: Articles section (timeline layout, filter system, featured cards)
- Phase 1d: Single article (meta bar, share sidebar, footer nav, progress bar)
- Phase 1e: Photo gallery (lightbox, grid layout, shortcode updates)
- Phase 1f: Static pages (about/contact page layout)
- Phase 1g: 404 page (standalone HTML, quote randomization, recent articles)

New files:
- 6 CSS components: hamburger, article-hero, share-sidebar, timeline, lightbox, 404
- 8 JS modules: hamburger, glitch, typing, scroll-reveal, share-sidebar, lightbox, 404, photo-utils
- 6 template partials: article-single, featured-card, photo-article, share-sidebar, static-page, timeline-item
- 1 layout: 404.html (standalone)

Updated:
- All CSS variables with comprehensive token system
- All JS modules integrated into main.js
- All shortcodes (gallery, gal-img) for lightbox compatibility
- All layout files (baseof, home, section, page) with new dispatching logic

Verified: Hugo build succeeds with 21 pages, no errors.
