/*
ART DIRECTION: "A private museum with one careful owner"
Concept: a deadpan gallery of 200 pairs of trainers. Warm cream walls, shoebox red,
brass labels, charcoal ink. A serious curator's voice attached to very silly objects.

PALETTE
--cream   #F4EDE0  page background (the gallery walls)
--paper   #FBF7EF  cards, exhibit mats, the hero tag
--tint    #E8DCC5  alternate bands and wing backgrounds
--ink     #231F1D  body text and headings (about 15:1 on cream)
--shoebox #A8231B  action red: buttons, stamp, big numbers (white text about 7:1)
--brass   #6E5420  small labels on cream (about 6:1)
--deep    #1E1A18  announcement bar and footer
--gilt    #C9A24B  hairlines and ornaments on dark backgrounds (about 7:1 on deep)
--placeholder #F1E3B8 highlight behind [bracketed] details still to be confirmed

TYPE
Display: Cormorant Garamond (high-contrast serif for headings and the wordmark)
Text: Inter (catalogue labels, body copy, buttons)

MOTIF
Museum tags: paper tags with a punched hole and a fine gilt inner border (hero card, lot cards).
A tilted red "Not for sale" stamp. Lot numbers set like gallery labels. A gilt ornament divider.
A faint grain on the cream walls.
