   DeltaFlowprint — global stylesheet
   Single source of truth. Previously this exact CSS was pasted
   into BOTH header.php (lines 88-283) and index.php (lines
   57-220), shipping ~2x the bytes on every page load and risking
   the two copies drifting apart. Now loaded once, cached for a
   year via .htaccess (see Cache-Control rules), shared by every
   page. Run through a minifier (e.g. `npx clean-css-cli`) before
   final deploy — this copy is kept readable for maintenance.
