pipe-coupling.astro has a FAQ UI section (4 Q&A) but was missing
the FAQPage structured data. Added faq prop to BaseLayout so the
schema renders automatically via the existing JsonLd.astro
component.
Now all 3 pages with FAQ UI (realflex, เทอร์โมเบรค-thermobreak,
pipe-coupling) have matching FAQPage JSON-LD schema, which helps
Google rich results + GEO (Google AI Overview, Perplexity, etc.)
surface the FAQ content.
FAQPage schema renders as:
{
"@type": "FAQPage",
"mainEntity": [
{"@type": "Question", "name": "...", "acceptedAnswer": {"@type": "Answer", "text": "..."}},
...
]
}
