To "upd" a theme is to iterate with humility. Release changes as small, reversible steps. Version variables: --theme-name, --theme-version, --theme-date. Offer a simple toggle to revert. Document decisions: why shadows deepen here, why hue shifts there. Treat users as co-curators; their preferred posters and layouts are as meaningful as your aesthetic.
