- nginx: allow robots.txt/sitemap.xml explicitly, fix error_page to 404.html, deny _template.html, remove txt from deny list, fix API proxy comment
- Convert residential.png to residential.webp per image SOP
- components.css: mobile nav breakpoint 768→1023px, 360px ultra-narrow query, overflow-x:clip, inline grid collapse overrides
- blog/index.html: placeholder blog listing page with 3 article cards
