/* styles.css - mobile-first. Base styles target phones (360px+); min-width media
   queries add layout as space grows:
     600px   large phones / small tablets portrait: header on one row
     900px   tablets landscape / small laptops: current + hourly side by side
     1200px  desktops: 7-day list gets its own column
   Fluid type (clamp) and auto-fit grids handle everything in between. */
