   Challenge Inkidia — /inkidia_defi
   Palette and type scale taken from the client's reference design.
   Everything is prefixed .c2- so it cannot collide with the website theme,
   with inkidia_landing.css or with inkidia_challenge.css.
   Logical properties (margin-inline, inset-inline) are used throughout so the
   Arabic (RTL) block mirrors correctly without a second stylesheet.
