/* Sensorman ERP house stylesheet - mobile first, no JavaScript.
   Look kept as before: light background, white cards, navy headings, Segoe UI 13 px baseline.
   Phone rules live in the max-width:720px block; the desktop table look is restored above 720 px.
   Served from /static/erp.css so the page needs no inline <style> (CSP script-src 'self'). */
