feat: add standalone FAQ page and remove FAQ from index

[C4aZy]

📝 Description

Moved the FAQ section from index.html into a dedicated standalone page (faq.html) to keep the main page focused on projects and the playground.

Changes Made

New File

• web-app/faq.html — standalone FAQ page with:
  • Sticky header with logo and theme toggle
  • Hero section with title and subtitle
  • All 8 FAQ accordion cards (keyboard accessible)
  • Dark/light theme synced with localStorage
  • Footer with GitHub link
  • Full SEO meta tags, OG/Twitter cards, JSON-LD FAQPage schema

Modified Files

• web-app/index.html

  • Removed <section class="faq-section"> block
  • Removed dead FAQ accordion IIFE from inline JS
  • Added faq.html link to footer Quick Links
  • Added faq.html link to footer-bottom-links

• web-app/sitemap.xml

  • Added faq.html URL entry

Why

The FAQ section was cluttering the main projects dashboard. Moving it to its own page gives the playground section more focus and makes the FAQ easier to find and link to directly.
