/* Prompt Packs: hub (/prompt-packs) + pack pages (/prompt-packs/<slug>).
   Builds on the site tokens in /index1.css (dark theme), the same base as /techniques/.
   Every class is .tpk-* so nothing here can restyle the shared nav or footer.
   CLS: all text is server-rendered; JS-only buttons keep their box (visibility, not display) until the script runs;
   example outputs start closed; no images load inside the content column. */
