/* ============================================================
   Zagros ERP — standalone frontend polish (loads AFTER app.css)
   Design decisions follow the dataviz method:
   - values/labels wear INK, never the brand color (color = marks only)
   - stock bars: ONE green fill (single measure), 4px rounded ends,
     light track, 2px gaps, direct labels in ink
   - status pills keep color + TEXT (validated set: gray/green/red/amber)
   - recessive grids, thin marks, tabular numbers
