/* ============================================================================
   Career guide — stylesheet
   Mobile-first. BEM naming: block__element--modifier.

   Breakpoints, as specified: 375 / 768 / 1024 / 1440.
   Note that 375 is not written as a media query. Mobile-first means the base
   rules ARE the 375 layout; a `min-width: 375px` query would only exclude the
   360px Androids that make up a large share of this audience.

   Everything degrades: with CSS loaded but JS off you still get a working TOC,
   a working FAQ, readable skill bars and a scrollable college list.
