   Farmer Membership Management System — base stylesheet
   A small, self-contained utility/component CSS framework (no external
   CDN or build step required). Class names are Bootstrap-5-compatible
   so templates stay readable, but this is a lightweight original
   stylesheet, not the Bootstrap library itself — the app ships fully
   offline-capable without needing to fetch anything after install.
