/*
 * Template "Putri Duyung" (Ulang Tahun): an enchanted under-the-sea party for a little mermaid.
 * Colors from the variant (<x-inv.head>): --inv-primary (aqua sea), --inv-deep (deep ocean teal, also buttons),
 * --inv-accent (coral pink: shells, ribbons, the cover button), --inv-background (pearl sand), --inv-text (ink on
 * light sections), --inv-pearl (cards and ink on deep water), --inv-gold (rims and small accents).
 * Section tones (class putri-duyung-tone--deep|light|accent, set in index.blade.php) alternate down the page; each
 * tone sets the section tokens --pd-fg (text), --pd-fg-soft, --pd-title, --pd-eyebrow, --pd-line, --pd-glass,
 * --pd-glass-line, --pd-top (its top color, used by the wave edge). Text always sits on calm water or a pearl card.
 * Pacifico only for the child's name; Fredoka for titles; Nunito for everything else.
 * Motion only under html.inv-anim (off with "reduce motion"); scroll-driven parts inside @supports.
