/* ==========================================================================
   style.css — ArawHome Solar (placeholder brand)
   Mobile-first base styles. Larger breakpoints live in responsive.css.

   Design notes
   - Palette: white paper, night-grid navy text, solar gold for action,
     leaf green for energy/sustainability.
   - Type: Archivo (variable width). Expanded widths for headings and key
     figures give a "spec plate" feel; normal width for reading text.
   - One memorable element: the hero energy-flow scene with its inverter
     readout. Everything else stays calm.
