   Temporary "Coming soon" page - wine tourism / the estate as a whole.

   Official estate palette (sampled from the logo, 2026-07-08):
       gold     #D49834  - primary colour (ROSO wordmark); site accent
       bordo    #3A1027  - base/background, "DOURO WINE ESTATE" claim
       cream    #F2EAE3  - text on dark background
   Typography: Fraunces (display serif) + DM Sans for body/support.
   NOTE: the terracotta/terra/olive system belonged to the RESTAURANT
   manual (Grape & Steak). The estate is gold-forward - see README.
