/* Hallmark · genre: editorial · macrostructure: custom bespoke (centred, single-purpose ordering site)
 * nav: N1b SaaS three-section · footer: Ft2 Inline single line
 * theme: custom (tuned) — RED field oklch(28% 0.15 24), GOLD ink oklch(80% 0.11 78), cream cards for dense info
 * pattern: hand-built 回纹 (huí wén) key-fret / nested-square meander, the traditional Chinese border motif — Tier-A SVG, not a generic lattice
 * display font: Domine (bold) — closest free match to the client's own carved-gold shopfront lettering (bracketed slab serifs, rounded bowls)
 * enrichment: E8 hero photography relocated to Find Us as tilted, overlapping prints (the "come see us" moment, not decoration with no job)
 * motion: hover-triggered gold shimmer + static grain/noise texture on primary buttons (Tier-A SVG feTurbulence, ported in spirit from Aceternity's noise-background)
