/*
 * Galaksi Celestial — "celestial night: moon, constellations & stardust".
 * Deep midnight navy/indigo + soft gold foil + a dusky violet/rose nebula glow, alternating with pale moonlight-ivory
 * sections that carry Dürer's engraved star chart. Real public-domain images in ../img (see img/CREDITS.md):
 * moon.webp (the full Moon; phases are masked from it here), nebula.webp (Rosette Nebula, used as a mask and tinted
 * by the variant), star-chart.webp (Dürer 1515, used as a mask, inked in the variant's deep gold).
 * Fonts: the client's pair (--inv-font-display names, --inv-font-heading titles) + Jost for reading and labels.
 * Variant colors: --inv-primary, --inv-accent, --inv-background, --inv-text, --inv-sky, --inv-nebula, --inv-rose,
 * --inv-surface, --inv-deep, --inv-label, --inv-ink, --inv-star, --inv-ivory. All template classes start with "gc-".
