/* SUPPLY.training — shared header, footer, search and small site-wide fixes.
   Every rule is scoped to .sx-* classes with element+class specificity, so page styles that target
   header / nav / footer / a cannot change these parts, and these rules cannot change the pages.
   Inserted by tools/build-site.js — edit this file, then re-run the build. */
