Add background_effect (aurora/particles), background_overlay tint and
opacity to the theme manager, rendered site-wide by ThemeVars on every
public page. Polish the home and register pages (hero mascot, live stat
pulse, date pills, photo strip, CTA band, theme-aware register intro,
i18n for home/register section).
Theme Manager under /admin-next/hotel/theme-manager lets the owner save, apply, rename, delete, import, and export custom themes, plus set a custom site background by URL or upload. Themes are stored in WebsiteSetting/custom_themes JSON so they survive CMS updates.
