I’ll build this as a complete advanced citation stylesheet for RX Theme: citation chips, reference boxes, medical evidence badges, footnotes, DOI/PubMed links, responsive behavior, dark mode, print mode, accessibility, and WordPress block compatibility.

Yes friend — create this file:

assets/css/rx-citation.css

Then paste the full code below.
