/* Listing cards and the homepage filter row, in the mem0 design language.

   Lives here rather than in main.css because existing template-asset URLs
   pin stale at the origin (see docs); a fresh filename serves fresh bytes.
   Superblog only auto-links its fixed list of names, so partials/nav.html
   links this by hand, guarded on assetsUrl. The pcard-* names are fresh for
   the same reason: the stale main.css still carries the old .card rules.

   Flat selectors only — the upload pipeline has dropped nested (&) rules. */
