/*
 * Template "Bintang Kecil" (Tujuh Bulanan & Baby Shower) — a dreamy lullaby night, "Twinkle twinkle little star".
 * Deep midnight navy and indigo with rich gold, a warm peach/coral glow and soft cream. Signature pieces: the crib
 * mobile (sections/_mobile) over the nursery window with a puffy cloud edge (sections/_window), the star sky with
 * dotted gold constellations (sections/_sky), quilted cream cards with dashed stitches and scalloped cloud tops
 * (.bkc-quilt), constellation dividers (sections/_divider), and the scratch-off gold star of the reveal
 * (sections/reveal + js/bintang-kecil.js). Mobile-first, one column (~460px) on a night backdrop on wide screens.
 *
 * Colours come from the chosen colour variant (template.json → <x-inv.head>):
 *   --inv-primary (indigo / violet / teal / rose: titles, buttons, glows)   --inv-accent (gold foil)
 *   --inv-background (cream)   --inv-text   --inv-deep (the night bands, the cover)   --inv-night (the darkest sky)
 *   --inv-shine (light gold on dark)   --inv-soft (peach: the peach tone, cloud undersides)   --inv-coral (warm accents)
 *
 * Section tones (set on each section in its partial): .bkc-tone--night (starry navy), --cream (quilted cream),
 * --peach (warm peach). Motion only runs with html.inv-anim (set by <x-inv.head> unless the guest prefers reduced
 * motion); without it everything is shown finished.
 *
 * Revision standard (docs/template-guide.md section 10): the cover is sized in px steps per screen height, never
 * svh/vh; ornaments hang beside the window's shoulders, never over faces; photos melt into sections with masks;
 * the closing is compact and its names end above the bottom menu.
 *
 * Contents: 1 base · 2 tones · 3 shared pieces (heading, divider, quilt, sky, mobile, window, rub marker)
 *           · 4 cover · 5 sections in page order · 6 forms · 7 shared components · 8 screen sizes · 9 motion
 *           · 10 intro scene
