/* ---------- shared .pd- text, bumped one size up (Anthropic page only) ----------
   This bump was requested specifically for the Anthropic page. These classes live
   in partnerdetail.css and are shared with Databricks AND with OpenAI (both also
   use the .pd- primitives), so the bump is scoped under body.ai-page-anthropic
   (set from page.slug in partner_page.html) rather than body.ai-standalone, which
   would silently also enlarge OpenAI's text to a size never asked for there - a
   real bug this page had until fixed here. Editing the source in partnerdetail.css
   directly would also resize Databricks' text, which is why this stays a scoped
   override rather than a source edit. */
