/* Sophemy design system.
   Brand: a confident blue for action, certificate gold for achievement, deep navy for
   the moments that set the tone (hero, closing call to action, footer). Green and red are
   kept for right and wrong. One typeface, Inter, self-hosted: Inter Display for headlines,
   Inter for everything else. The test screen stays calm and focused, like real exam software. */
