/* ==========================================================================
   Product page (pages/product_page.php).

   Depends on:
     - the --pub-* tokens in wpl-public-theme.css (light/dark)
     - the shared primitives in wpl-landing.css (.pub-shell, .pub-card,
       .pub-chip, .pub-btn, .pub-eyebrow, and the .pub-rail carousel, which
       this page reuses verbatim for its two related-books rails)
     - two classes from wpl-week-listing.css that this page borrows rather
       than restates: .wk-card-variant (the badge on the cover) and .wk-note
       (the incentive-variant callout). Neither sheet is loaded here, so both
       are defined at the bottom of this file.

   Namespacing: --pd-* / .pd-* is this page. See the note at the top of
   wpl-public-theme.css for how --pub-*, --wpl-*, --wk-* and --sp-* divide up.
