/* Bank Clerical Prelims — product UI.
   Method borrowed from Advox: true-neutral greys so the accent never bleeds
   into surfaces, a real 1.08:1 card lift instead of borders doing the work,
   a contrast-verified ink scale, and an accent that is rationed rather than
   sprayed. Every ratio below was measured, not guessed.

     #1A5CFF on #FFFFFF ......... 5.23:1   (AA body, and white on it is also
                                            5.23:1, so filled buttons carry
                                            white text safely)
     #0B44C8 on #FFFFFF ......... 7.85:1   accent text and links
     ink      #161718 ........... 17.95:1
     ink-soft #4C4D4E ...........  8.47:1
     muted    #696A6B ...........  5.42:1
     faint    #8D8E8F ...........  3.28:1  labels and icons, never body
     surface over canvas ........  1.08:1  the card lift
