Add 5 long-form Thai blog posts (1,200-2,500 words each) with SEO + GEO optimization for the dealplustech water-systems site. Each post targets a specific audience (contractors, engineers, project managers) and follows a content-quality workflow: source real product specs, verify Thai text, dedupe images, link back to product pages. ## New blog posts (src/content/blog/) - thermobreak-guide.md (Thermobreak closed-cell insulation overview) - plastic-grilles-guide.md (ABS plastic grilles for HVAC) - ppr-pipe-guide.md (PPR pipe properties + heat-fusion welding) - ppr-vs-hdpe-vs-upvc.md (3-way pipe comparison with PE80/PE100) - thermobreak-series-guide.md (Thermobreak LS vs Solar series) - 10-things-checklist-pipe-ordering.md (10-point pre-order checklist) ## Removed legacy posts - pipe-knowledge.md, valve-guide.md, welcome-post.md (orphans) ## Hero images (public/images/blog/) ~20 product photos sourced from manufacturers (Thermobreak, Thai PPR, thaiconsupply) plus Nano Banana Pro infographics. All resized to 3:2 aspect ratio per user preference. Source folder preserved for re-derivation. ## Astro layout/SEO work - src/components/seo/SEO.astro, JsonLd.astro (new SEO components) - src/layouts/BaseLayout.astro, Layout.astro (OG/Twitter/JSON-LD wiring) - src/pages/404.astro - Product pages (8): added #pricelist anchors + schema work - src/styles/global.css: scroll-padding for sticky-header anchors ## Automation scripts (scripts/) - build_og_image.py (OG image builder) - inject_faq_schema.py, inject_product_schema.py (JSON-LD injection) ## Misc - public/robots.txt, public/images/og/default-og.jpg - .gitignore: exclude scripts/__pycache__/
