   HABISCOPE · DESIGN SYSTEM (ds.css)
   Shared by the application (index.html) and the administration (admin.html).
   The public pages (commune.css) mirror the same tokens.

   RULE: every new screen reuses these tokens and components. No raw native
   control (select, checkbox, file...) and no decorative inline style: only
   truly dynamic values (a bar width in %, a computed colour) stay inline.
