Bead pattern generator: turn images into perler / fuse-bead patterns in the browser (sampling + color limit), with grid/hole preview, palette stats, and PNG export — /imagetools/beadpattern
Image pixelate: mosaic / pixel-art effect locally in the browser; adjustable block size and PNG download — /imagetools/imagepixelate
Leaner pages: removed duplicate bottom SEO intro blocks from Home, Mini Program, About, and Donation; kept page body and tool lists

Tool docs as Markdown: interactive tool footers load Content/**/*.md (same Description + Markdig pipeline as the regex tester) for easier maintenance and better SEO / GEO; removed duplicate short blurbs
Site-wide SEO / GEO: bilingual titles, descriptions, keywords, full sitemap paths, FAQ/HowTo structured data, and llms.txt; home title fallback fixed
