/* web/static/css/learn.css
 *
 * Styling for the Learn exercise screen (screens/learn/exercise.js).
 * Calm and theme-driven: every colour comes from a CANONICAL CivNode theme
 * variable (--bg-primary, --text-primary, --accent, ...) so the screen follows
 * the active theme. Fallbacks are dark (midnight is the default theme); they
 * are only ever reached if a theme variable is somehow undefined.
 *
 * The hard rule honoured here is NO layout shift -- the result area reserves
 * vertical space so a PASS/FAIL never jumps the page. Pass is a quiet success
 * tone, fail a gentle diff, never an alarming red wall.
