   SyntaAI — Prompt Library styles
   Additive to /articles/agent-article.css (shared nav, footer,
   hero, content, callout, cta, table tokens). This file only
   adds what's specific to the Prompt Library: index cards,
   the free/mode chip, the verbatim prompt block + copy button,
   the source-table intro, and the optional email capture.
