   CML Dashboard — Mobile Stylesheet
   ----------------------------------------------------------------
   Loaded AFTER each page's inline <style> block to override.
   Breakpoints:
     phone:  max-width 640px  (iPhone portrait primary target)
     tablet: max-width 1024px and min-width 641px (iPad)
     desktop: ≥1025px — untouched, current design wins
   Naming:
     - All new utility classes prefixed m- to avoid collisions
     - Existing class names (.sidebar, .header, .kpi-card, etc.) only
       overridden inside media queries
