External links in post bodies now open in a new tab and show a box-with-arrow marker icon, so readers can tell at a glance which links leave the site. - blogex: new Blogex.ExternalLinks.rewrite/1 marks up anchors with http(s) hrefs at compile time with target="_blank", rel="noopener" and class="blogex-external" (idempotent, merges into existing class/rel values, leaves relative, mailto: and #anchor links alone) - blogex: Post.build/3 applies the rewrite, so every blog gets it - app: CSS in .blogex-post-body draws the marker via a mask so it inherits the link colour; empty ::after content stays invisible to screen readers - make test now also runs the blogex suite; it is currently red with 3 pre-existing blog_integration_test failures caused by the vacuous link validator (parked yak link-validator-never-sees-compiled-html-...)
