/* Zambarau (plum) — moody, dramatic, editorial: the first dark-toned theme
   in the lineup (the other five are all light/airy). Deliberately scoped
   dark treatment, not a full dark-mode inversion — only the Hero and RSVP
   moments go dark (background: var(--zb-ink)), every other section still
   sits on the theme's normal light --zb-blush body background, so this
   drops into the same palette[1]=ink/palette[2]=bg architecture every
   other theme (and lib/inviteCard.js) already assumes, with none of the
   engineering risk a whole-site dark-mode pass would add. Signature
   details: the dark full-bleed hero with a soft gold radial glow behind a
   large italic serif wordmark, and an offset "gallery wall" — a staggered
   grid (odd columns pushed down) with thin gold hairline frames, no theme
   repeats another's gallery technique (Dhahabu: masonry, Bahari:
   horizontal-scroll, Kijani: polaroid-scatter, Waridi: magazine-collage,
   Machungwa: trimmed-border grid). Structurally closest to Waridi (full-
   bleed dramatic hero, asymmetric Location) but the typography (elegant
   italic serif, not bold uppercase sans) and every color/shape are
   Zambarau's own. */
