   Kids International School — custom styles (plain CSS)
   The Tailwind Play CDN only compiles utility classes found in the HTML; it
   does NOT process @apply inside external stylesheets. So all component styles
   here are written as plain CSS using the brand palette directly.

   Brand palette:
     blue      #1E40AF   blueDark #172E7C   blueLight #0369A1
     sky       #EFF4FF   yellow   #FBBF24   yellowDark #F59E0B
     ink       #0A0A0A
