/* Shared styles for the content pages (/ai-text-expander, /gmail-templates, …).
   The homepage keeps its own inline CSS — it is one big bespoke layout and is
   already live, so it is deliberately NOT refactored onto this file. What lives
   here is the subset those pages share: the design tokens, the nav/footer
   chrome, and the article typography the homepage has no use for.

   Served from /assets/, which _headers caches for 30 days. Bust it by bumping
   the ?v= on the <link> in each page when you edit this file. */
