[WIP] Polish pass: accessibility, reduced-motion support, nav glow centering, and minor UI fixes

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original description:

Goal

Create a pull request that (1) keeps the new glow + squiggle + section toggle behavior already added to index.html, (2) fixes the slight centering issue (already handled via display:inline-block), and (3) performs a final polish pass for accessibility, robustness, and small quality-of-life improvements.

Summary of Improvements Implemented

1. Accessibility / Semantics
   • Added <meta name="description"> for SEO / link previews.
   • Added role="navigation" and aria-label to <nav>.
   • Added aria-current="page" on the active nav link (removed when not active).
   • Ensured nav links are keyboard focusable with a custom visible focus ring (without disturbing layout) for better a11y.
   • Added title attributes to external/social links for assistive tooltip context.
2. Reduced Motion Support
   • Added @media (prefers-reduced-motion: reduce) to disable large background animation, blob float, and squiggle draw for users who prefer less motion.
3. Defensive / Progressive Enhancements
   • Added a small JS guard so if flower.jpg fails to load it adds a subtle fallback message (avoids broken image icon vibes).
   • Encapsulated section switching logic a bit more cleanly and added comments for future-you.
4. Minor Visual Polish
   • Added a subtle focus-visible outline for nav links (contrasting brand color #d57624) distinct from hover transform.
   • Tweaked glow pseudo-element vertical position a hair (from -10px to -8px) so the torch-glow looks more centered under shorter link text.
5. Misc
   • Added a favicon placeholder comment hook (easy future add).
   • Added code comments explaining the squiggle animation and glow illusions.

File Changed

• index.html

Testing Notes / How to Verify

1. Load page normally: gradient animates, blobs float, squiggle draws, nav glow appears on active link.
2. Click a nav link twice: first click opens section, second returns to intro (existing behavior preserved).
3. Use keyboard (Tab) to move through nav links: focus outline appears. Enter/Space triggers navigation logic (default anchor behavior suppressed but JS runs).
4. In OS/browser reduced-motion setting: gradient stops animating; squiggle draws instantly; blobs stop floating.
5. Open DevTools, simulate offline for flower.jpg (or temporarily rename): fallback message appears instead of broken image icon.

Requested Review Points

• Confirm the glow looks centered now with inline-block + adjusted offset.
• Confirm reduced-motion styles feel acceptable (can tweak to fully remove squiggle if desired).
• Confirm aria-current toggling works (inspect in Elements panel while switching tabs).

Included Change

Below is the updated index.html (full replacement).
