/* Make It Easy · Student Space
   Look: a light, friendly teaching platform. White pages, one main colour (indigo blue) for buttons, links and the
   key word, one warm second colour (orange) for small highlights and the current level. Both work in day and night mode.
   Plus Jakarta Sans for English, Cairo for Arabic.
   Motion: calm, with real depth (CSS 3D). Only "transform" and "opacity" move, so it runs at the screen's own refresh rate.
   To change the colours, change the six values on the next line (main, darker, lighter; second, darker, lighter). */
