Blog list (/blog): add robots, full Open Graph + Twitter, Blog +
BreadcrumbList JSON-LD, per-page self-canonical, and rel=prev/next for
paginated pages.
Blog post: add robots, og:site_name, article:published_time /
modified_time / author / section, twitter:image, og:image:alt, and a
BreadcrumbList JSON-LD (Home → Blog → Category → Post).
Gallery (/gallery): add robots, full OG + Twitter (with first image as
og:image), ImageGallery + BreadcrumbList JSON-LD.
Encoding: register HtmlEncoder.Create(UnicodeRanges.All) so Persian text
in meta tags and JSON-LD renders literally instead of &#xXXXX; entities
(smaller, cleaner output; friendlier to SEO validators).
