/* explore.css
   -----------
   Styles for the STANDALONE /explore/ and /explore/<slug>/ pages. These are the
   pages a shared link lands on, and what search engines index.

   Deliberately its own small stylesheet rather than a copy of the landing page's
   inline CSS: this is a different design problem (a quiet reading page, not a
   two-sheet stack), so sharing would mean carrying ~50KB of stack, install-card
   and overlay rules that none of these pages use. Same tokens, same fonts, same
   ground, so it still reads as one site. Follows the /learn + learn.css
   precedent already in this repo.

   Bump the ?v= in the generated <link> whenever this changes: the URL caches hard. */
