   CARDS COMPONENT
   NOTE: this app's card surfaces (.r-block, .formulation-card,
   .dr-card, .gender-card, .summary-pills, etc.) currently each
   declare their own background/border/radius rather than sharing
   one base rule — they were authored independently across several
   feature passes. Unifying them under one shared class would mean
   editing the HTML's class attributes, which is out of scope for a
   "reorganize, don't change the UI" refactor. They are intentionally
   left in their owning feature stylesheet (report.css, gender.css,
   whatsapp/lead-capture.css) rather than moved here unused.
   Flagged here as the clear next step for a future cleanup pass.
