   Gallerí — The Curated Wall
   Brand: Kauply — íslensk smávöruverslun sem hangir verkin upp
          eins og á sýningu. A small Icelandic shop that presents its
          goods like a hung exhibition: matted, captioned, accessioned.
   Identity: transparent header floating over an edge-to-edge plate,
             one dominant Sorts Mill Goudy display voice, generous
             museum negative space, and a SIGNATURE accession-number
             caption — every product is "Nr. 01 — Heiti verks" with a
             hairline plaque rule, like a wall label beside the work.
   Motif:    accession plate (CSS counter, decimal-leading-zero) +
             passe-partout mat frame on the PDP. No other theme has this.
   Fonts:    Sorts Mill Goudy (display) + Chivo (body) — consumed from
             injected --font-display / --font-body.
   Palette:  consumed from injected --text / --surface / --accent etc.
             via color-mix; NEVER hardcoded so each store recolours.
