     #030630  Midnight     (deep shadow tone)     -> surface-deep
     #F9EEDF  Parchment    (crest highlight)      -> cream
     #BBB0A8  Stone        (crest mid-tone)       -> muted
   Heritage accents harmonised with Oxford Blue:
     #C9A227  Gold         -> CTA / accent
     #7B1E2B  Burgundy     -> secondary accent / badges
