  /* TENANT: EuroTier Charity Auction - bid.eurotier.com
     Brand source: https://www.eurotier.com/en/ (DLG / TYPO3 bootstrap theme)
       EuroTier navy   #003377  (bs-primary, nav highlight, links, main buttons)
       EuroTier navy dk #00295F (darker navy)
       EuroTier green  #7FC243  (bs-secondary, sustainability / growth tone)
       Font            Source Sans 3
       Radius          0.375rem (sharper than the WeAuction default)

     Charity context: proceeds above the set minimum prices go to charitable
     organisations (e.g. German Children's Fund, WeReforest). The palette pairs
     EuroTier's institutional navy with its green as the "giving / reforest"
     call-to-action color, so Bid / Register buttons read as an act of support.

     Contrast (WCAG): white on accent #3F7D20 = 5.0:1, white on primary #003377 = 12.1:1,
     navy on secondary #EEF6E7 = 10.9:1, muted text #5C6670 on white = 5.9:1.
     EuroTier's own green #7FC243 fails AA with white text and as text on white,
     so it is used only as --accent-soft (hover tints / highlights).
