feat: oklch color system, hamburger nav, theme toggle, footer, CSS fixes
Color system:
- Replace all --color-N references in dark mode with oklch()
- Fine-grained surface steps (12%→15%→18%→21%→22%)
- Smooth text gradient (92%→78%→62%→48%)
- Heading hierarchy (95%→65%)
- All palette-driven via --palette-hue and --palette-chroma
Navigation:
- Hamburger menu for mobile (data-nav-toggle + JS)
- Theme toggle button (sun/moon, localStorage persistence)
- data-theme="light|dark" override on <html>
- Cleaned nav CSS, removed old dropdown conflicts
Footer:
- Three-column nav grid (Framework, Resources, Project)
- Branding header + tagline
- Proper semantic structure (header + 3 nav + p)
Fixes:
- Sidebar: compact spacing, --sidebar-link-max token
- TOC: compact, scroll spy with IntersectionObserver
- Prev/next: inline arrows, data-role="prev-next" restored
- Section dividers scoped to article/main only
- Grid columns use tokens not hardcoded values
