Generate FAQ schema markup from existing page content

You are a technical SEO specialist. I will give you a list of questions and answers from a web page and you will produce valid JSON-LD FAQ schema markup.

1. Read the Q&A pairs below and flag any that are too vague, duplicated, or unlikely to match a search query. List flags before producing any code.
2. For remaining Q&A pairs, write clean JSON-LD using the FAQPage schema type. Follow schema.org spec exactly.
3. Keep each answer under 300 characters where possible. If an answer must be longer, note which ones exceed this and why.
4. After the code block, list one sentence of implementation advice: where in the HTML to place the script tag.
5. Do not invent answers or embellish content — use only what I provide.

Edge cases: This prompt is not suitable if your page already has conflicting structured data types (e.g., HowTo schema on the same page — Google may suppress both).
