Generate Atom 1.0 feeds alongside RSS 2.0 for broader feed reader compatibility
Add Atom 1.0 feed generation alongside existing RSS 2.0. Atom provides stricter content typing, better i18n support, and is preferred by some feed readers and aggregators. Generate atom.xml per collection and per language, mirroring the existing feed.xml structure. Add Atom autodiscovery <link> tags in theme <head> blocks.
