Fix design system compliance: CSS variables, accessibility, and theme system

Core CSS improvements:
- Add --surface-rgb, --type-* (tech, life, quote, link, photo) custom properties
- Add --type-* semantic color classes for article badges
- Convert article badges from inline styles to CSS variable system
- Add prefers-color-scheme light fallback for no-JS users
- Add prefers-reduced-motion support to respect user accessibility settings
- Replace *:focus with *:focus-visible (keyboard-only outlines)
- Add clamp() fluid typography for hero-title and section-title
- Refactor container rules to mobile-first with 1060px breakpoint

Theme & Icon fixes:
- Fix theme toggle icon display with Alpine.js (was broken with Tailwind dark: classes)
- Add aria-hidden="true" to icon elements
- Update header with proper ARIA attributes on menu toggle

Accessibility enhancements:
- Add skip-to-main-content link in baseof.html
- Update hamburger menu with aria-expanded, aria-controls, aria-hidden
- Implement focus trap (Tab loops) within mobile menu
- Return focus to trigger button on menu close
- Add menu open/close state management with proper ARIA

Semantic HTML:
- Wrap article pages in <article> element (articles/single.html, _default/single.html)
- Fix quote article to use --type-quote border color instead of generic accent

Image optimization:
- Add loading="lazy" to profile image in index.html
- Add loading="lazy" to featured image in photo.html

Template fixes:
- Remove broken os.Getenv "THEME" runtime check from article-list-item.html
- Replace inline color styles with semantic .type-* classes
- Add 1060px lg: breakpoint to tailwind.config.js

i18n updates:
- Add skipToContent translations (en, it)
