/* ========================================================================
   Career Advice — page styling on top of tokens.css + resources.css.

   An article hub (category chips + premium cards) and an in-page reader
   (hide the hub, show one article without leaving the page). Every rule is
   scoped to a `.ca-` wrapper so nothing leaks; no :root redefinition, no
   color-mix(). Headings use var(--font-secondary); cards use the shared
   premium recipe (1px gray-200 border, radius-lg, soft shadow).
