/*
 * Golden Milestone (Ulang Tahun, dewasa): "a golden jubilee dinner, refined luxury".
 * A deep ground (emerald by default) with real metallic gold and champagne ivory. The age is the hero: a huge
 * classic engraved gold numeral resting on the gold-framed arch with the client photo, flanked by laurels.
 *
 * Colors from the variant (template.json → <x-inv.head>):
 *   --inv-background (the deep colour), --inv-deep2 (its darker end), --inv-text (ivory text on deep),
 *   --inv-panel (cards on deep), --inv-primary (gold text on deep), --inv-accent (light gold),
 *   --inv-foil1 / --inv-foil2 (deep and light ends of the metallic foil),
 *   --inv-ivory (the light ground), --inv-ink (text on ivory), --inv-goldink (gold text on ivory).
 * Rhythm: the sections of <main> alternate automatically between DEEP (odd) and IVORY (even) by nth-of-type, so
 * hidden sections never break it; an ivory section redefines --inv-background / --inv-text / --inv-panel /
 * --inv-primary locally, so every rule below simply follows. The closing is always deep.
 * Motion only with html.inv-anim (off with reduced motion): every drawing is then shown finished.
