/* The public developer pages (/developers/*, lib/developers_pages.php).

   Built on /account/shell.css (linked just before this file): its column
   (.account-page), cards (.account-card) and buttons (.account-btn) are the
   same objects here, so the docs read as part of the account people already
   know. Every color is a --cat-* token from themes/base.css, which resolves
   across all nine themes and carries the light-theme overrides; nothing here
   is hardcoded. Selectors stay under .dev-page because footer.php re-loads the
