On screens, display brightness and glare can also interfere. Check that your code uses a dark pattern on a light background, maintains a clear four-module quiet zone on all sides, and meets the size requirements for your expected scanning distance. Test on multiple devices to confirm compatibility.","inLanguage":"vi"},"inLanguage":"vi"}]}},"_links":{"self":[{"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/posts\/2418","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/users\/17"}],"replies":[{"embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/comments?post=2418"}],"version-history":[{"count":4,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/posts\/2418\/revisions"}],"predecessor-version":[{"id":54969,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/posts\/2418\/revisions\/54969"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/media\/54415"}],"wp:attachment":[{"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/media?parent=2418"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/categories?post=2418"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/tags?post=2418"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
