/*
 * Template "Putri Duyung" (Ulang Tahun): an under-the-sea party for a little mermaid.
 * Colors from the variant (<x-inv.head>): --inv-primary (the sea), --inv-deep (deep water, also buttons),
 * --inv-accent (coral: the cover button, ribbons, shells), --inv-background (sand), --inv-text (ink on light
 * water), --inv-pearl (cards and ink on deep water).
 * The page is one dive: sunlit shallow water at the top (dark ink), a reef drop-off, then deep water (pearl ink)
 * down to the sandy seabed. Text always sits on calm water or on a pearl card, so it stays readable.
 * Pacifico only for names and section titles; Nunito for everything else.
 * Motion only under html.inv-anim (off with "reduce motion"); scroll-driven parts inside @supports.
