/* Olevel — olevel.ng
   Nunito stays the voice. What makes this read modern is borrowed structure:
   saturated colour rather than washed pastel, mono caps labels at wide
   tracking, a handwriting face for asides, a faint canvas grid, and cards that
   tilt on hover.

   Important: the accents below are the LOGO's colours, not the app's exam-card
   colours. The card colours (#d8cce6 etc.) are heavily desaturated — right as
   quiet backgrounds in the app, weak as a website palette. The logo already
   carries the saturated versions. */
