Better fix for TOC showing previous article headings. The issue was
relying on pathname which could be out of sync with the actual content.
Changes:
- Pass contentKey as prop to PostToc instead of using usePathname()
- Use contentKey in useEffect dependency for more reliable updates
- Replace setTimeout with double requestAnimationFrame for DOM sync
- Remove unused usePathname import
This ensures the TOC effect runs exactly when the content changes,
not just when the URL changes, providing more reliable synchronization
between the TOC and the article content.

Adjusted TOC button positioning to prevent overlap with the back-to-top
button on mobile devices:
- Mobile: bottom-20 (80px) - sits well above back-to-top at bottom-6
- Desktop: lg:bottom-8 - maintains original desktop position
- Both buttons now aligned to right-4 on mobile for consistency
This gives ~56px vertical spacing between buttons on mobile,
preventing any overlap while keeping both easily accessible.

The TOC toggle button was appearing near the end of posts instead of
floating at a fixed position. This happened because the button was
rendered inside the PostLayout component hierarchy.
Changes:
- Use React Portal to render TOC button at document.body level
- Add mounted state for proper SSR/client hydration
- Button now floats like back-to-top button, visible from start
This ensures the button is always visible and accessible, similar to
the back-to-top button behavior.

Problem: Table of Contents displayed headings from previously viewed
articles when navigating between posts via client-side routing.
Root cause: PostToc component's useEffect with empty dependency array
only ran once on mount, so it retained stale heading data when React
reused the component instance during navigation.
Solution: Add contentKey prop flow:
- Blog/page routes pass slug to PostLayout
- PostLayout passes contentKey as key prop to PostToc instances
- React remounts PostToc when key changes, rebuilding TOC correctly
Files changed:
- components/post-layout.tsx: Add contentKey prop and key forwarding
- app/blog/[slug]/page.tsx: Pass slug as contentKey
- app/pages/[slug]/page.tsx: Pass slug as contentKey
