/* LMS Overview landing page. The look is the extension's own: a quiet cool neutral, one ink-blue accent for
   anything you can click, IBM Plex Sans for reading and IBM Plex Mono for numbers, soft tinted fills for
   status. Light and dark are designed from one token set. Borders are uniform or absent, never on one side only. */
