/* ==========================================================================
   GTAC-MGI Application Portal — shared stylesheet

   Brand values are taken from https://gtac.wustl.edu. The public site was
   sampled directly (computed styles, not guesswork); the design language it
   uses and this file follows is:

     - Source Sans Pro throughout, headings 600–700, set LARGE
     - navy #20325f dominant, teal #7cc3b9 as solid accent blocks,
       crimson #cc3366 as the tertiary action accent
     - fully-rounded pill buttons, uppercase, letter-spaced
     - generous vertical rhythm, full-bleed colour bands

   If the public site is ever restyled, update the tokens in :root below and
   every page follows.
